Rapid prototyping of a multivariable control with pole placement by state feedback of a PMSM: LMI approach

This paper introduces a multivariable state feedback controller for the speed and stator current control of a PMSM. The desired performances are obtained through proper poles placement in D regions using LMI approach. The proposed controller is evaluated in simulation and experimentally. Simulation and experimental results indicate that the proposed control is reliable and effective for the speed control of the PMSM over a wide range of operations of the PMSM drive.
