Abstract

This paper proposes an improved permanent magnet synchronous drive system. By suitably adjusting the three-phase current commands, the switching frequency of the drive system can be abruptly reduced. In addition, the three-phase currents maintain balanced sinusoidal waveforms. An optimal control is designed to achieve high performance dynamic responses which include a fast transient response and a good load disturbance rejection capability. A 16-bit microprocessor system (MC 80196) is used to execute the improved control algorithm. Several experimental results validate the theoretical analysis. This paper presents a new direction in the design and implementation of a permanent magnet synchronous drive system
