This book was released on 2017 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this work, a model-free sliding mode control technique for linear and nonlinear uncertain multi-input multi-output systems is proposed. The developed method does not require a mathematical model of the dynamic system. Instead, knowledge of the system’s order, state measurements, and control input gain matrix shape and bounds are assumed to develop the control law and drive the system’s states to track a desired trajectory. The control system relies on estimating the error between previous and current control inputs to stabilize the system. Lyapunov’s stability criterion is used in the derivation process to ensure closed-loop asymptotic stability. High frequency chattering of the control input and higher-order states, often observed with the sliding mode control method, is eliminated using a smoothing boundary layer. Simulations are performed on a variety of linear and nonlinear systems, including a quadrotor model, to test the performance of the control law. Finally, the model-free sliding mode control system is modified to account for the effects of actuator time-delays."--Abstract.

Book excerpt: "Bioinspired flight serves to balance the advantages of fixed-wing flight as well as traditional rotary systems. A flapping wing aerial system exhibits high maneuverability at low speeds like a rotary system and the higher efficiency that fixed-wing systems exhibit in forward flight. A method to actuate a flapping wing structure is using piezoelectric elements. Using flapping wings to perform aerial maneuvers and facilitate stable flight will require precise control of the piezoelectric elements and control surfaces. The focus of the research is the construction of a feedback control platform for the flapping wing aerial system. For any type of feedback control architecture, an accurate way of estimating the current state of the system is required for precise tracking control. Since the control system will be implemented in an aerial vehicle, the system must be lightweight to allow for a larger payload capacity for the aircraft. Nonlinearities arising from uncertainties and unmodeled environmental effects lead to changes in the system model and a linear control scheme will exhibit suboptimal performance and instability. The desire of this aircraft to be able to perform under different flight conditions make determination of an accurate system model a time-consuming and vast undertaking. These flight conditions include take off, gliding, and landing under different wind, pressure, temperature, and payload specifications. Sliding Mode Control and Lyapunov-based methods have been explored extensively due to their capability of handling nonlinear systems directly while guaranteeing stable tracking control. However, determining an appropriate model to approximate the system dynamics is difficult and can lead to undesirable results. These variations can be accounted for by using a model-free control approach. In this work, a model-free controller based on the Sliding Mode Control method implemented for a flapping wing aerial system is considered. The model-free control algorithm only requires knowledge of the system parameters such as the order of the system and state measurements. The algorithm has been implemented successfully in traditional unmanned aerial systems achieving adequate control of system states. While the goal is for the Model-free algorithm to be implemented on a flapping-wing unmanned aerial system, at the time of this thesis, the construction is still in progress. Therefore, an analogous system was built to test the algorithms. A balancing system consisting of a DC motor and propeller mounted to a servo motor for thrust vectoring was constructed. A linear controller derived from the system model was compared in simulation and testing to the Model-Free Sliding Mode Control algorithm."--Abstract.

In addition, some other important issues related to MFAC are also discussed. They are the MFAC for complex connected systems, the modularized controller designs between MFAC and other control methods, the robustness of MFAC, and the symmetric similarity for adaptive control system design. The book is written for researchers who are interested in control theory and control engineering, senior undergraduates and graduated students in engineering and applied sciences, as well as professional engineers in process control.

Download or read book Model free Sliding Mode Control in the Lateral and Direction Dynamics of an Aircraft written by Nicholas Hutson and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Traditional control methods require extensive tuning or a derivation of a system model making them increasingly antiquated for use on new, more complex systems. Sliding Mode Control has emerged as a more effective alternative as a control method that can directly handle nonlinear systems with increased robustness while guaranteeing stability. However, it is still limited by the need for a system model for the derivation of the controller form. This work proposes a new model-free control method based on Sliding Mode Control referred to as Model-Free Sliding Mode Control where the form of the controller is only dependent on system order, state measurements, and previous control inputs. Lyapunov’s stability theorem is used to ensure global asymptotic stability and a boundary layer is incorporated to reduce chattering. The model-free properties of the controller are enabled by a least-squares online parameter estimation method used to estimate the control input influence gain matrix of the system directly. The estimation process is essential as previous work was limited by assuming the bounds of the control input influence gain matrix are known or the assumption it was unitary. The estimation method also incorporated exponential forgetting to only include updated data for parameter estimation, increasing the speed of convergence. Another addition was a bounded gain forgetting factor to ensure that the magnitude of the control input influence gain was upper bounded. The performance of this controller was simulated on various example systems to test its performance. These included single-input, single-output and multi-input, multi-output first and second order systems. Principally, the controller was implemented to control a lateral-directional state space model of an aircraft with a shaped input characterizing aircraft roll and yaw dynamics. The controller proved to exhibit outstanding tracking performance, convergence of estimated parameters, smooth and acceptable control input, and increased robustness to parameter uncertainty. Therefore, the controller was proven to be a feasible method to control the lateral and directional dynamics of an aircraft."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: AfterasurveypaperbyUtkininthelate1970s,slidingmodecontrolmeth- ologies emerged as an e?ective tool to tackle uncertainty and disturbances which are inevitable in most of the practical systems. Sliding mode control is a particular class of variable structure control which was introduced by Emel’yanov and his colleagues. The design paradigms of sliding mode c- trol has now become a mature design technique for the design of robust c- troller of uncertain system. In sliding mode technique, the state trajectory of the system is constrained on a chosen manifold (or within some neighb- hood thereof) by an appropriatecontrolaction. This manifold is also called a switching surface or a sliding surface. During sliding mode, system dynamics is governed by the chosen manifold which results in a well celebrated inva- ance property towards certain classes of disturbance and model mismatches. The purpose of this monograph is to give a di?erent dimension to sl- ing surface design to achieve high performance of the system. Design of the switching surface is vital because the closed loop dynamics is governed by the parameters of the sliding surface. Therefore sliding surface should be - signed to meet the closed loop speci?cations. Many systems demand high performance with robustness. To address this issue of achieving high perf- mance with robustness, we propose nonlinear surfaces for di?erent classes of systems. The nonlinear surface is designed such that it changes the system’s closed-loop damping ratio from its initial low value to a ?nal high value.

This book was released on 2019 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Control methods require the use of a system model for the design and tuning of the controllers in meeting and/or exceeding the control system performance objectives. However, system models contain errors and uncertainties that also may be complex to develop and to generalize for a large class of systems such as those for unmanned aircraft systems. In particular, the sliding control method is a superior robust nonlinear control approach due to the direct handling of nonlinearities and uncertainties that can be used in tracking problems for unmanned aircraft system. However, the derivation of the sliding mode control law is tedious since a unique and distinct control law needs to be derived for every individual system and cannot be applied to general systems that may encompass all classifications of unmanned aircraft systems. In this work, a model-free control algorithm based on the sliding mode control method is developed and generalized for all classes of unmanned aircraft systems used in robust tracking control applications. The model-free control algorithm is derived with knowledge of the system’s order, state measurements, and control input gain matrix shape and bounds and is not dependent on a mathematical system model. The derived control law is tested using a high-fidelity simulation of a quadrotor-type unmanned aircraft system and the results are compared to a traditional linear controller for tracking performance and power consumption. Realistic type hardware inputs from joysticks and inertial measurement units were simulated for the analysis. Finally, the model-free control algorithm was implemented on a quadrotor-type unmanned aircraft system testbed used in real flight experimental testing. The experimental tracking performance and power consumption was analyzed and compared to a traditional linear-type controller. Results showed that the model-free approach is superior in tracking performance and power consumption compared to traditional linear-type control strategies."--Abstract.
