摘      要：Precise position tracking control of the single-rod pneumatic actuator is considered and a nonlinear cascade controller is *** proposed controller comprises an extended disturbance observer(EDOB)and a nonlinear robust control law synthesized by the backstepping *** EDOB is designed to estimate not only the influence of disturbances but also the parameter *** the use of parameter and disturbance estimates,the nonlinear cascade controller,which consists of an outer position tracking loop and an inner load pressure loop,is further designed to attenuate the effects of parameter and disturbance estimation *** stability of the closed-loop system is proven by means of Lyapunov *** comparative experimental results obtained verify the effectiveness of the proposed nonlinear cascade controller and its performance robustness to parameter and external disturbance variations in practical implementation.
