摘　　要：基于三菱可编程控制器PLC设计,直接对调速步进电机进行控制,以三菱PLC移位SFTR指令作为步进控制的核心,设计的调速梯形图程序简洁、清晰、柔性、可靠,调试结果完全满足柴油机调速的控制要求。Based on the design of Mitsubishi PLC( programmable logic controller), speed control step motor can be controlled directly with the Mitsubishi SFTR command as the core of step control. The designed speed control ladder diagram program is concise, distinct, flexible and reliable, and the commissioning result fully satisfies the requirement of diesel engine's speed control.
