A Continuous Output Feedback Finite-Time Speed Tracking Control of PMSM

A finite-time speed tracking control for a permanent-magnet synchronous motor (PMSM) is presented. The proposed control scheme depends on finite-time convergence of a fractional power differential equation. A continuous feedback controller for a PMSM is constructed based on the double integrator form of PMSM with a tricky coordination transformation. The simulation results show its efficiency.
