Nonlinear control of permanent magnet synchronous motor with limitations constraints

In this paper, a nonlinear control has been developed for a permanent magnet synchronous motor (PMSM), in order to perform tasks with minimal execution time. This control method takes in consideration the PMSM limitations´ constraints: stator´s current must be within the safety specifications. PMSM´s nonlinear model is proposed. Nonlinear control methods have been developed for the various states of limitations. Simulation results have been presented. This developed control´s method overcomes any disturbances in real time and obtains significant execution time gain.
