High-Performance Speed Control of Induction Motor Using Combined LSSVM Inverse System

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 113)


In this paper, a new speed control method based on combined least squares support vector machines (LSSVM) inverse system for induction motor is proposed. It is characterized by that feedback of rotor flux and inverse model building are combined through LSSVM training and fitting. Firstly, LSSVM is used to build the inverse model of induction motor from the input–output data, and the inverse mode is served as the basis for the inverse controller design. The combined LSSVM inverse is composed of a LSSVM to approximate nonlinear mapping, an integrator and a differentiator. Cascading the LSSVM inverse with induction motor, induction motor system is transformed to a pseudo-linear system. Finally, simulation of the control method is performed to validate its feasibility. The results show that presented method has clear dynamic structure, which is effective for induction motor control.
