Design of High Speed Hydraulic Position Servomechanisms Using Optimization Techniques

Abstract

This paper collates and extends recent research on the design of hydraulic position servomechanisms using optimization techniques in place of conventional linear feedback methods. Different methods of control are proposed on the basis of a formal application of time optimal control theory followed by an analytical study of the time optimal controller. Optimum designs for the proposed controllers are then derived using a digital computer simulation and parameter optimization sub-routines. Finally, the performance of the proposed controllers is compared with the best performance that can be achieved using conventional proportional control.
