A GENERAL INVERTER BASED ON CLOSE-LOOP FLUX LOCUS CONTROL USING DIGITAL SIGNAL PROCESSOR (DSP)

摘要

A general purpose inveiter based on close-loop flux control method has been developed. By using DSP, the contradiction existing between the complexity of algorithm and the demands of real time control can be solved easily. This paper focus on the design, implementation, and performance improvement of the system. Computer simu- lation and experimental results show that the system is of high steady and transient performances with the sampling time of 100us, and the current distortion factor is less than 10%.
