Adaptive Control of a Synchronizing Servo-System

An implicit recursive pole placement self-tuning control algorithm is used for the adaptive control of an electro-hydraulic synchronizing positioning servo-system. An error feedback gain is optimised on-line by adaptively using the method of the golden mean. Experimental results illustrate that the system exhibits good dynamic performance and adaptive property. The usual difficulties associated with the control of an electro-hydraulic servo system, such as the provision for fast response, time-varying parameters and nonminimum phase properties, are solved as a result of using the algorithm.
