通用逆变器变频闭环调速系统

A Frequency-Regulated Closed-Loop Speed Control System

本文介绍了由通用逆变器、异步电动机、测速发电机和模拟控制器所组成的变频闭环调速系统,详细论述了P—I调节器、I—P调节器和转差频率调节器的设计方法。实验结果表明,用标量控制所获得的性能指标,以I—P控制较好,转差频率控制最好。

This paper introduces a frequency-regulated closed-loop speed control system, which comprises a general inverter, an induction motor, a tachometer, an analog controller. The design methods of P-I, I-P and slip regulator are discussed in detail. Experimental results obtained by using of scalar control method show that the I-P regulation is better than P-I regulation in performance, and the slip regulation is best among the three kinds of regulation.
