Available in PDF, EPUB and Kindle. Book excerpt: In North America one of the main users of primary energy are buildings, where HVAC equipment operation is the largest consumer of total energy by end use. This has triggered the need to develop better active strategies and building technologies for the enhancement of HVAC equipment performance. Great examples of solutions that large commercial and institutional buildings adopted, were the widespread use of Building Automation Systems (BAS), and approaches like Variable Air Volume (VAV) systems for ventilation, which allow for better part load regulation, reduction of energy consumption and building operation costs, without compromising occupant comfort or safety. But despite all these improvements, most BAS still rely on conventional control methods like rule based on-off control paired with Proportional Integral Derivative (PID) loops, which are single input single output (SISO) models that are not suitable for the complexities of the multivariable requirements of building systems. These outdated strategies have been estimated to annually waste up to 30% of building's energy. To mitigate these issues the research community has strongly endorsed the use of more advanced and proven effective control methods such as Model-Based Control (MBC), in which abundant work has been done for the supervisory level control like optimal start/stop, setpoint reset scheduling, etc. However, little attention has been given to local level control where PID control remains the chief workhorse of HVAC systems. Mainly because of the difficulties of creating models, as well as the lack of research regarding the implementation of mechanisms required for continuous calibration (also known as adaptability) of model parameters as they start to drift away from their initial values due to system changes or deterioration, which challenges the reliability of any MBC approach. For such reasons the present body of work was conceived to design a practical methodology for a self-adaptive MBC and field data driven approach to improve VAV systems energy efficiency, based on the Total Air Volume (TAV) control method by modifying the shortcomings of its modeling, adaptability and control strategy procedures. Using a regular VAV system inside a high-rise institutional building as an experimental testbed for the proof of concept of this methodology. The results of the test demonstrated that the self adaptive field calibrated TAV method can match and exceed the capabilities of PID control, by improving response time, offset, and above all energy efficiency, were an average 56% of energy consumption was achieved in contrast to the conventional duct static pressure PID control.

Download or read book Development of a Self adaptive Model Reference Automatic Control System written by P. H. Zavod and published by . This book was released on 1967 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automatically controlled systems frequently employ proportional plus integral devices as the controller in the closed loop. The determination of the optimum values of the coefficients of the proportional and integral terms is normally accomplished by trial and error procedures. In an effort to obviate this procedure, a method was developed to compute the optimum values of gain and integration constant of a conventional proportional plus integral controller using an analog computer operating iteratively and in fast time. The results of this computation were applied directly to the settings of a controller in a closed loop system operating in real time. The speed of the optimization process was such that the optimum controller settings were determined for a disturbance after the disturbance had taken place but before the process had responded to any significant degree.

Download or read book Virtual Equivalent System Approach for Stability Analysis of Model based Control Systems written by Weicun Zhang and published by Springer. This book was released on 2021-06-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book puts forward the concept of a virtual equivalent system (VES) based on theoretical analysis and simulation results. The new concept will facilitate the development of a unified framework for analyzing the stability and convergence of self-tuning control (STC) systems, and potentially, of all adaptive control systems. The book then shows that a time-varying STC system can be converted into a time-invariant system using a certain nonlinear compensation signal, which reduces the complexity and difficulty of stability and convergence analysis. In closing, the VES concept and methodology are used to assess the stability of multiple model adaptive control (MMAC) systems and T-S model-based fuzzy control systems.

This book was released on 1971 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The equations describing the dynamic properties of a typical non-linear load disturbed system were derived with the objective of developing a superior control system in this application through use of analog computer function optimization techniques. The automatic control systems generally used in this application employ proportional-plus-integral devices as the controller in the closed loop. The determination of the optimum values of the coefficients of the proportional and integral terms is normally accomplished by trial and error procedures. In an effort to obviate this procedure, the method developed computed the optimum values of gain and integration constant of a conventional proportional-plus-integral controller using an analog computer operating iteratively and in fast time. The results of this computation were applied directly to the settings of a controller in a closed loop system operating in real time. The speed of the optimization process was such that optimum controller settings were determined for a disturbance after the disturbance had taken placed but before the process had responded to any significant degree.
