Abstract

In this paper, a new approach to nonlinear control (NC) of induction motors is presented. This approach consists of a novel direction in the development of controllers for the rotor flux amplitude and the motor speed. The proposed approach shows that the nonlinear motor dynamics can be linearized and decoupled by means of feedback-linearization techniques. A comparative study is carried out between the performances of the nonlinear controller and field oriented control (FOC) using the simulation results, which show that the NC operates quite robustly under external disturbances and it can provide good dynamic performance such as no overshoot and fast transient time in the speed control.
