【Abstract】 The non-symmetry pump-cylinder system is widely used in various-speed field, which is inherently nonlinear, time variant and subjected to intensivedisturbance. In this paper, a PID controller is proposed to approach the nonlinear anti-model of the object, and to realize the control of electro-hydraulic swash-plate position and flow, so that the uncertainty and nonlinear of the system can be compensated. The resultsof simulation and experiment show that the proposed PID controller can conduct nonlinear control and improve the performance of the control system.更多还原
