Predefined-Time Control of Full-Scale 4D Permanent-Magnet Synchronous Motor

Abstract

This paper presents a predefined-time convergent robust control algorithm that allows the control designer to set the convergence time in advance independently of initial conditions. The control law is consequently designed and verified by simulations for a full-scale 4D Permanent-Magnet Synchronous Motor (PMSM) system in cases of both completely and incompletely measurable states. Numerical simulations are provided for a full-scale 4D PMSM system to validate the obtained theoretical results in each of the considered cases. To the best of our knowledge, this is the first attempt to design a predefined-time convergent control law for multi-dimensional systems with incompletely measurable states.
