Robust control applied induction machine employed of Matlab/ Simulink

Abstract

This work refers the approach of a control strategy/metodology for control of the induction machine in high performace. The classic method presented in the literature [1], they are composed of controllers PID’s acting in the strategy of control of the speed of the machine. The mathematical model of the induction machine after an appropriate treatment, equaly leads to the mathematical model of the machine of continuous current, which the control strategy is much simpler. The proposal of this work was to use of a new control methodology that is more reliable and mainly robust and that assists the performance requirements and stability. It is be described that the method of Robust Control showed the robustness conditions, stability and performance.
