Laguerre Function’s Based Model Predictive Control of Three Phase Induction Motor
Electrical drives play a vital role in industrial and domestic applications, so these drives must be more efficient and easy to control. Conventional control methods are well established and nearly fulfill all demands of modern electrical drives but there is still a need to improve these controllers. In this paper it is proposed that the conventional field oriented controllers can be replaced by Model Predictive Controllers (MPC) which are currently being used as process controllers. These MPC controllers are preferred over conventional field oriented controllers because they can predict future behavior of system and according to that predicted value they can adjust their present input in order to minimize the error signal. The major drawback of conventional MPC is that a lot of mathematical iterations are required to predict the future behavior of system so Laguerre function’s based MPC model is used to reduce the mathematical effort and results are validated for a three phase induction motor.
