| Research Abstract |
In this research project, novel generalized computer-aided design and high performance control scheme have been developed for salient-pole AC motors. Remarkable achievements in the project are summarized as follows ;
1.Based on a mathematical model of salient-pole AC motors which is formed by both "a simple Permeance Method" and "a precise Finite Element Method", the optimal design algorithm of rotor construction can be established.
2.By using dimensions and parameters obtained by the proposed design algorithm, an autonomous constitution of motor control laws can be established. The autonomous controller can realize torque ripple free drive, acoustic noise free drive, and maximizing of torque-current ratio.
3.The effectiveness of above design and control algorithms have been verified by experiments using reluctance motors.
4.Position and speed sensorless control scheme for salient-pole brushless DC motors has been developed. The sensorless control algorithm is based on the rotor saliency and can estimate the rotor position in low speed range, as well as in the middle and high speed ranges. In experiments using a prototype, the speed control range from zero speed to 3,000 rpm from no-load to the rated load conditions can be achieved.
The achievements obtained by the project have been published in journals and proceedings of The Institute of Electrical Engineers of Japan and The Institute of Electrical and Electronics Engineers (USA).
