摘要：Induction motor drives are widely used in industries for its simple and easy control. Variable structure controller (VSC) for an induction motor drive is an effective method of control in case of non linearities and uncertainties to enhance robustness. Dynamic performance of Induction motor drives is an essential characteristic for many industrial applications. Quality of the product is an industry and the profit of the industry are mainly depends on the performance of the induction motor drive. Transient state performance of the VSC based an induction motor drive to be improved. Since conventional VSC based induction motor drive has PI controller based speed controller. To enhance the performance of the system this paper proposes Model reference Adaptive System based speed controller in VSC. The design is simple and easy to be implemented. The entire system is simulated using Matlab / Simulink to analyze the performance of a drive. Performance of a drive using Model reference Adaptive System VSC is analysed and compared with conventional Proportional and Integral VSC. To analyze the dynamic performance of the system machine is subjected to constant and variable load in this paper.
