Parameter Compensation of Induction Motor Drives Using Second order of Sliding Mode Controller
Authors: , ,
Abstract: The continued operation of vector controlled induction motor drives faces problems related to the stator and rotor resistance variation due to saturation, skin effect or in temperature variations. These resistance variations affect the controller performance. This paper illustrates a new closed-loop approach for evaluation followed by compensation of stator and the rotor resistance of an induction motor by using the method of second-order sliding mode controller. The motor resistances estimated by online and the fault between the actual and the desired state variables of the motor track the sliding surface, the proposed method is established on the rigorous Lyapunov stability criteria. The simulation results show that the high-frequency variation in output waveform is reduced as compared to classic sliding mode controller and the mathematical analysis which is simple and reduces the complexity facedby the higher order controller. For the estimation of the control variables of the proposed algorithm, only current measurement is needed and the controller is independent of the unknown parameter variation as the property of the sliding mode controller. The proposed method has been analyzed and verified with the help of Matlab/Simulink.
