Abstract

Induction motors are widely used in industry and many other fields due to robustness, reliability, low price and free maintenance. The control task is complicated by the fact that induction motors are subject to unknown disturbances and the parameters are of great uncertainty. This paper presents a differential flatness-based controller for induction motor vector control system. The flatness-based approach uses the characterization of system dynamics to generate a suitable output and it can control continuous nonlinear systems with good performances in term of tracking trajectory. Simulation results shown that the flatness based control scheme can improve the control performance effectively.
