RESEARCH ON AUTO-DISTURBANCE-REJECTION-CONTROL FOR SLIP POWER RECOVERY INDUCTION MOTOR
A double-closed-loop control system based on auto-disturbance-rejection-controller (ADRC) is presented to improve the dynamic performance of sllp power recovery motors. In which, ADRC is used as auto speed regulator (ASR) and conventional proportional-integral-derivative (PID) controller is used as auto current regulator (ACR). By using tracking differentiator (TD), a desirable transition response can be defined to reduce overshoot when input signal changes. The model uncertainty and external interference can be accurately estimated and compensated to a form of integrator series by the extended state observer (ESO). Without integrator, the control law is a nonlinear function of state error and its differential. The simulation results of this control strategy for motor drive show that the design of the control system does not rely on mathematical models. This system has strong anti-disturbance capacity, fast response, nearly non-overshoot, so the system dynamic performance is improved in contrast with the conventional PID controller.
