This paper deals with a nonlinear control strategy of induction motor that combines an input-output linearization control technique and a nonlinear observer design. It is well known that induction motors are the most widely used motors in electrical appliances, industrial control, and automation. However, it is also known that induction motor control is a complex task that is due to its nonlinear characteristics. Two main features of the proposed approach are worth to be mentioned. Firstly a nonlinear control is carried out using a nonlinear feedback linearization technique involving non available state variable measurements of the induction motor system. Secondly a nonlinear observer is designed to estimate these pertinent but unmeasurable state variables of the machine.
The circle-criterion approach is performed to compute the observer gain matrices as a solution of linear matrix inequalities (LMI) that ensure the stability conditions of the estimated state
error dynamics of the designed observer in the sense of Lyapunov. Simulation results are presented to validate the effectiveness of the proposed approach.
