Title: The role of a modular multi-microcomputer controller in position control systems

Abstract: The work reported in this thesis is concerned with the application of digital control techniques to position control. The major emphasis is devoted to the use of modular multi-microcomputers as real-time controllers. Minicomputers and microcomputers do not always meet the technical requirements of modern system design; the modular multi-microcomputer controller is the most appropriate choice in many high performance systems. The specification, design and construction of a modular multimicrocomputer controller is described. The controller has been applied to an electro-hydraulic cylinder position control system, where emphasis has been given to the control of load damping. The control system design is based on the use of state-space methods. Optimal control and observers are used. Experimental tests are reported for open and closed loop. The open-loop results show the particular characteristics of an asymmetric cylinder drive. The closed-loop results show the behaviour of the drive under a simple digital proportional controller and a state-variable controller. variables such as position, velocity, cylinder pressures and piston thrust are displayed for several test conditions.
