高速精密轧辊磨头主轴驱动控制系统设计
Design of spindle drive control system of high-speed precision roll grinding head
摘要
Abstract
High-speed roll grinder,w hich is based on high precision and stabilization electrical con-trol system,is an indispensable equipment in steel production fields to achieve accurate control of the grinding process .Aiming at a kind of high-speed roll grinder whose grinding speed was more than 80 m／s,with the FX3UPLC as controller,the PLC (programmable logic controller ) analog control unit was formed by using the supporting standard A／D and D／A special function module of PLC,and the spindle drive control system of high-speed precision roll grinding head was de-signed based on FX3UPLC and frequency converter .T he requirement of high-speed precision roll grinding head on its electrical control system was described,and the variable frequency speed-ad-justing control system was introduced with the constitution,controlling scheme and signal-dis-posal methods .The hardware circuit,motor speed control trapezoid chart and analog control sys-tem communication program were designed .In addition,by using Kingview software,the PC monitor screen was developed,and the motor speed was set up by the input box of PC software, and the analog encoder was taken as the feedback sensor of output speed of the spindle motor .At the same time,the PID speed closed-loop control system was added to make spindle motor oper-ate smoothly by the given speed .The PLC was adopted to carry on the on-site collection to the analog signal through the mathematical model calculation and signal feedback of the operating en- vironment .Finally,the entire control system realized the on-line adjustment of the spindle motor output speed and the real-time detection of the process variables and ran steadily,w hich had good anti-interference performance and ensured the continuous and reliable,safe and efficient operation of the high-speed precision roll grinding head .关键词
