MODEL REFERENCE ADAPTIVE CONTROL FOR TIME VARYING HYDRAULIC SYSTEMS

摘要：

This paper focus on adaptive control of an electric-hydraulic servo position control system, in which an optical-elelectric pulse coder is used as the position feedback sensor. The pressure feedback and MR AS controller are introduced to enhance the system damp ratio and proper frequency. Using Matlab as a tool, a theoretic analysis and digital simulation have been made to show that the pressure-feedback MR AS controller has high accuracy, good dynamic character and strong robust while the system parameters changed at different oil temperature.
