A high performance PWM inverter voltage-fed induction machines drive with an alternative strategy for speed control

Abstract

In this paper, the method of behaviour model control is applied to an induction motor with its mechanical load in order to increase the robustness of the vector control and to keep its performances despite the presence of perturbations (parameters variations, abrupt load variations, etc). The idea of the proposed control is interesting and useful. It induces adding supplementary control inputs, which yield the process to follow the model. The distinguished feature of this control design is that it achieves the same performances as the Field Oriented Control without the need for heavy and expensive gain tuning. The proposed strategy minimizes the energy used for the control and ensures the stabilization and excellent tracking performance of the system. Simplicity of the method, minimization of the required energy and the elimination of the need for gain tuning are the main positive features of the proposed approach.
