摘　　要：针对多电动机驱动的大倾角带式输送机重载启动与停止时物料下滑或滚动等问题,建立了多机驱动大倾角带式输送机模糊控制算法,介绍了大倾角带式输送机总体控制模型、带式输送机的速度设定算法和功率平衡模糊PID参数自整定算法。应用结果表明,该模糊控制算法能够根据煤流量的实时变化自动调节带式输送机的运行速度,速度控制误差小于2%,功率控制误差小于2.5%,能使4台驱动电动机功率趋于一致,实现了四机驱动带式输送机可靠、安全、节能运行。In order to solve the problem of material＇s falling or rolling which occurs in starting and braking of high-inclination belt conveyor driven by multi-motor, a fuzzy control algorithm for high- inclination belt conveyor driven by multi-motor was established, and overall control model of high- indiration belt conveyor, speed setting algorithm of belt conveyor, and a fuzzy PID parameters self-tuning algorithm for power balance were introduced. The application shows that the fuzzy control algorithm can automatically adjust speed of belt conveyor according to real-time changes of coal traffic, it makes speed control error lower than 2 % and power control error lower than 2.5 %, enables power of four drive motors tends to the same, and achieves reliable, safe and energy-saving operation of belt conveyor driven by four motors.
