Abstract

This paper presents a nonlinear robust speed control for dealing with variations of the permanent-magnet synchronous motor (PMSM) stator resistance due to temperature changes. The change in resistance has a large impact on the slotless surface PMSM control performance due to its relatively large stator resistance in comparison with its inductance impedance. Nonlinear robust control eliminates the need for temperature sensing and is a suitable control approach for the frequently starting and stopping operation motor control. The controller takes into account the system nonlinearities and makes no requirements on the variation of the resistance. Therefore, it is full range operational. The Lyapunov stability proof is given in detail. The designed controller is shown to be efficient and robust with the simulation.
