Efficency Optimized Control for Closed-cycle Operations of High Performance Induction Motor Drive

Abstract

Algorithm for efficiency improvement of the high performance induction motor drive, based on the dynamic programming approach, is presented in this paper, along with performance index, constraints and system equations. For a given operating conditions in one periodical cycle, mathematical concept for optimal control is described so that the drive operates with minimal energy consumption. The procedure is described for a vector controlled induction motor drive, but procedures analogous to this one can be derived for other advanced techniques of induction motor drive control. Simulations and experimental tests have been performed.
