There has been proposed robust control the rotor mechanical angular speed of a surface mounted permanent magnet synchronous machine under conditions of parametric uncertainty. The perturbations have been bound with incomplete information about the structure mathematical model and parameters of the control object. Consequently, a field oriented control system has the considerable degradation of transient processesof electrical and mechanic coordinates. The improve performance the quality of transition processes in system with cascade control decides by means of the application control algorithms based on the concept of inverse problems of dynamics combined with the minimization of the local instantaneous energy values functional.
