针对郑州某选矿厂一段圈流磨矿回路,设计了一套以模糊控制技术和智能PID控制相结合的控制系统。模糊控制器以最佳参数电耳电流的变化情况作为二维输入,通过模糊优化算法获得给料机在一个计算周期内的最佳给矿量;利用智能PID闭环控制回路稳定给料,确保磨机具有高效、可靠、稳定的运行工况,简述了控制系统的实现。实际运行情况表明,控制系统具有很好的调控效果,满足了生产的需求。
For the first section of a mineral processing plant in Zhengzhou circle grinding circuit, a set of fuzzy control technology and intelligent control of a combination of PID control system. The fuzzy controller takes the change of the optimum parameter EEG current as the two-dimensional input, and obtains the optimal feed amount of the feeder in one calculation cycle through the fuzzy optimization algorithm; uses the intelligent PID closed-loop control loop to stabilize the feed, ensures that the mill Machine with efficient, reliable and stable operating conditions, outlined the realization of the control system. The actual operation shows that the control system has a good control effect to meet the production needs.
