摘　　要：针对气动位置伺服系统跟踪控制中系统受压力波动、摩擦力扰动等非线性因素影响较大的特点,提出基于压力反馈线性化、摩擦力补偿的内外双环型控制算法。仿真与实验结果表明,该算法结构简便又宜于实用、跟踪精度较高,控制效果较好。A position tracking control method for a nonlinear pneumatic servo system is proposed. The established control system has the inner pressure feedback linearization loop and the outer state feedback control loop with the friction compensator. Simulation results demonstrate that the control strategy has simple structure, high tracking precision and perfect control effect in applications.
