Observer Synthesis for an Asynchronous Machine Powered by an Voltage Inverter

The main objective of this work is to present the control and observation laws and their application on the asynchronous machine, and a comparative study of the performance of a vector control by conventional regulators and of a control with observer. This work will be devoted to the implementation of a state observer to improve the stability of the vector control of the asynchronous machine in the event that one of its internal parameters (such as stator resistance) varies. Simulation results will be redone to be able to judge the contribution of this observer to the performance and robustness of the control.
