Download or read book Statically Loaded Hydraulic Motion Control System written by Manik Kapoor and published by . This book was released on 2007 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project was to build a closed-loop hydraulic motion control system with a LabVIEW-based digital controller. The system consists of a weighted sled that moves along two parallel, horizontal guides, an electro-hydraulic actuation system, a sensor for measuring the position of the sled, and a LabVIEW-based, closed-loop control program. A phase-lead compensator was implemented into the control program to demonstrate the capabilities of the motion control system. The continuous design was accomplished by developing transfer function using system identification and control computations available in MATLAB. The corresponding discrete compensator was modeled in SIMULINK to evaluate its performance with a continuous closed-loop actuation system. The compensator was then incorporated into an existing LabVIEW code for closed loop control. The assembled system was used to demonstrate the effects of using a compensator and change in sampling rate on the performance of the motion control system. Experiments were performed to identify system parameters which would ensure optimum response in spite of using a proportional directional flow control valve.

Download or read book Motion Control in Offshore and Dredging written by P. Albers and published by Springer Science & Business Media. This book was released on 2010-06-10 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: High loads with high dynamics in severe conditions can only be driven by fluid power mechanisms. Motion Control is often used as a description in various engineering disciplines to refer to a technological solution that is able to control motion, e.g. the movement of at least one part relative to another. This volume describes how drives, sometimes very large, are designed and realised. The book gives a practical explanation of the way in which the different mechanisms described work. A distinction is made between rotating and linear drives. In the case of rotating drives, the choice for an electrical drive is becoming more and more prevalent. Linear drives remain important, because of the large forces and highly dynamic behaviour in the domain of hydraulic drive technology. Both these important technologies are extensively discussed in this book, together with design rules and the many installation requirements for applications in the offshore and dredging industry.

Download or read book Hydraulic and Electric Hydraulic Control Systems written by R.B. Walters and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force and motion control systems of varying degrees of sophistication have shaped the lives of all individuals living in industrialized countries all over the world, and together with communication technology are largely responsible for the high standard ofliving prevalent in many communities. The brains of the vast majority of current control systems are electronic, in the shape of computers, microprocessors or programmable logic controllers (PLC), the nerves are provided by sensors, mainly electromech anical transducers, and the muscle comprises the drive system, in most cases either electric, pneumatic or hydraulic. The factors governing the choice of the most suitable drive are the nature of the application, the performance specification, size, weight, environ mental and safety constraints, with higher power levels favouring hydraulic drives. Past experience, especially in the machine tool sector, has clearly shown that, in the face of competition from electric drives, it is difficult to make a convincing case for hydraulic drives at the bottom end of the power range, specifically at fractional horsepower level. A further, and frequently overriding factor in the choice of drive is the familiarity of the system designer with a particular discipline, which can inhibit the selection of the optimum and most cost-effective solution for a given application. One of the objectives of this book is to help the electrical engineer overcome his natural reluctance to apply any other than electric drives.

Download or read book Mobile Working Hydraulic System Dynamics written by Mikael Axin and published by Linköping University Electronic Press. This book was released on 2015-09-07 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with innovative working hydraulic systems for mobile machines. Flow control systems are studied as an alternative to load sensing. The fundamental difference is that the pump is controlled based on the operator’s command signals rather than feedback signals from the loads. This control approach enables higher energy efficiency and there is no load pressure feedback causing stability issues. Experimental results show a reduced pump pressure margin and energy saving potential for a wheel loader application. The damping contribution from the inlet and outlet orifice in directional valves is studied. Design rules are developed and verified by experiments. A novel system architecture is proposed where flow control, load sensing and open-centre are merged into a generalized system description. The proposed system is configurable and the operator can realize the characteristics of any of the standard systems without compromising energy efficiency. This can be done non-discretely on-the-fly. Experiments show that it is possible to avoid unnecessary energy losses while improving system response and increasing stability margins compared to load sensing. Static and dynamic differences between different control modes are also demonstrated experimentally.
