可编程序控制器双闭环串级调速系统的研究

Study on Double Closed Loop Cascade Speed Regulation System with Programmable Controller

阐述串级调速方法,引入电流内环和转速外环的双闭环控制,提高静态调速精度,获得较大的调速范围,较好的动态加速性能。探讨三菱PLC实现了双闭环串级调速系统的可逆与制动控制功能。

This paper expounds the cascade speed regulation method, introduces the double closed-loop control of current inner loop and speed outer loop, improves the static speed regulation accuracy, obtains a large speed regulation range and better dynamic acceleration performance. It discusses that Mitsubishi PLC realizes the reversible and braking control functions of double closedloop cascade speed regulation system.
