摘　　要：由于矿井温度控制过程具有非线性、振幅大等特性,传统PID控制难以达到理想的控制效果,为了提高温度控制的精度、响应速度以及稳定性,在传统PID控制的基础上,提出了一种参数自适应的模糊PID控制。利用MATLAB软件中的Simulink模块对这两种控制方式进行仿真模拟。结果表明:模糊PID控制解决了传统PID控制对非线性系统的控制效果不理想、振幅或偏差较大等问题,并且具有较强的适应性和鲁棒性。最后将模糊PID控制的矿井智能控温系统实际应用在通风系统较为复杂的山西某矿井内,解决了矿井通风量不足,自然风无法对矿井内温度进行稳定控制的问题,在有效提高温度控制的精度、响应速度、矿井的生产效率和安全性的同时,减少人力、物力资源的消耗。Because the process of mine temperature control has the characteristics of nonlinear and large amplitude,the traditional PID control is difficult to achieve the ideal control effect.In order to improve the accuracy,response speed and stability of temperature con-trol,a fuzzy PID control with parameter adaptive is proposed on the basis of the traditional PID control.Simulink module in MATLAB software is used to simulate these two control modes.The results show that fuzzy PID control can solve the problems of the traditional PID control,such as unsatisfactory control effect,large amplitude or deviation,and has strong adaptability and robustness.Finally,the mine intelligent temperature control system with fuzzy PID control is actually applied in a Shanxi mine with complex ventilation system,which solves the problem that the mine ventilation volume is insufficient and the natural wind cannot stably control the temperature in the mine.While effectively improving the precision of temperature control,response speed,production efficiency and safety of the mine,it reduces the consumption of human and material resources.
