【摘要】 本文论述了转差频率控制的异步电动机变频调速的基本控制规律和系统的构成。并通过对电流、速度双闭环调速系统的实验和调试,说明了该系统在一定程度上有类似于直流双闭环的静、动态特性。因而属于高性能的控制系统。更多还原

【Abstract】 This paper discusses the configuration and the basic control method of variable frequency and adjustable speed system of slip frequency cont rolled asynchronous motor via the experiment and anjustment’ for the current, speed and double closed-loop system and also explains that the system is similar to the static and dynamic charcteristics of DC double closed-loop to a certain extent, Thus it is a highhy-performed control system.更多还原
