Grey relational compensation control of pneumatic position servo system

摘要

For the tow tracking accuracy problem of pneumatic position servo control system, this paper proposed a new method of grey relational compensation control. Based on the geometrical similarity between control system's actual output and the desired output data sequences, this compensation controller could calculate the grey relational grade between them, design the grey compensation control law, and dynamically compensate for the control output of traditional controller. Simulation and experimental results show that: under the same controller parameters, the control effect with grey control compensation control is obviously superior to that with conventional controller, it effectively improves the tracking accuracy of pneumatic position servo control system achieved by traditional control method.
