Abstract
Applications of Permanent magnet synchronous motor(PMSM) are increasing widely because of its inherent advantages. The mathematical model of the motor is highly nonlinear. Designing controllers for nonlinear systems is challenging. It has been seen in the literature that approximate linear model with number of assumptions is used for controller design. In this paper our contribution lies in the development of a linear state feedback controller using the Jacobian linearization of PMSM, wherein the operating point is updated adaptively using Non Linear Disturbance Observer (NLDO). With this, we eliminate all three PI controllers used in the conventional vector control. Results are verified using MATLAB/SIMULINK simulations.
