Abstract

This paper presents a theoretical analysis of a maximum-torque-per-ampere control strategy based on the extremum seeking control working principle, which provides useful insights for the definition of a systematic and quantitative design procedure. The focus is on the convergence properties to the optimal operating point, and a method for evaluating an upper bound of the convergence time is proposed. The analysis is supported by several experimental tests performed on an interior permanent-magnet synchronous motor.
