机械电子式软起动控制系统的设计

本文在分析带式输送机的工作过程的基础上，对机械电子式软起动装置的控制系统进
行了研究，对控制系统进行了硬件与软件设计。使用可编程控制器对变频器的输出频率进行控制，实现对调速电机转速的控制。调速电机与主电机的转速经差动行星轮系的速度合成，可使传动系统在很大范围内无级调速，实现对负载的可控起动。

Abstract: On the basis of analyzing the working process of belt conveyor, the control
system of the mechatronics soft start equipment is studied，the hardware and software
are designed for control system. The programme logic controller is utilized to
control the inverter's output frequency which accomplishes controlling the
velocity of speed-controlling asynchronous moter .The velocity between main
asynchronous moter and speed-controlling asynchronous moter is composed by way of
the differential planetary gear train，the tranmission system is made to regulate
velocity stepless in large scope which succeed in controlling starting progress of
load.
