Adaptive Dynamic Surface Controller Design of Variable-Speed Pump Controlled Motor System with Parametric Uncertainties

摘要：

　　The constant speed control of variable speed pump controlled motor system is discussed in this paper. A dynamic surface controller is chosen to improve robustness of motor speed when rotational speed of variable pump is time-varying. In the presence of bounded parametric uncertainties, an adaptive control scheme with parameter estimation is presented. Load torque used in dynamic surface controller is observed via reduced order observer. The simulation results show that the proposed control scheme is robust to bounded parametric uncertainties. Adaptive dynamic surface control has a better rejection performance of pump speed variation and load torque disturbance than PID control.
