Description

This paper deals with a computer simulation method, which can realize high-speed and high-accuracy. The proposed method is characterized by both introducing the so-called discrete-time system with variable-sampling time and treating the digital control system as the discrete-time system with constant-sampling time. The proposed method is applied to a position-sensorless IPM motor drive system, which has been proposed by the authors. Simulated results show that the proposed method achieves more accurate and efficient simulation than conventional methods do.
