Advancement Through Research
In this paper a sliding-mode speed controller with torque feed-forward compensation is proposed. First, a sliding mode control method is presented. Then, in order to reduces chattering phenomenon caused by system parameter variations and external time-varying load torque disturbances, by using a cascade observer design technique based on the sliding mode control, a load torque observer and a load torque derivatives, a control method that merges the flexibility of the linear extended state observer (LESO) and SMC robustness is proposed to contribute with some important characteristics such as chatter-free performance, heftiness, robustness and secure power system operations. Simulation results obtained by Simulink/Matlab of the system proven the ability of this last one in reducing the chattering.
