High performance control of PMSM

Abstract

This paper proposed a new switching scheme for controlling permanent magnet synchronous motor (PMSM). The voltage source inverter (VSI) is represented as event driven system with 23 modes of operation. The switching among these modes is governed by the supervisory control approach. The salient future of the switching control is system order reduction, decoupling in the design procedure, insensitivity in plant parameter changes and disturbance rejection. Simple implementation makes concept of switching control very attractive in power electronic and electrical drives. The high performance hybrid control algorithm designed by proposed approach can be easily implemented on modern FPGA platforms.
