摘要
以高温马弗炉为被控对象,着重阐述如何在高温马弗炉的升温过程中将变论域方法与一般模糊PID控制两者结合起来,实现变论域模糊PID控制。这样,在一些对温度要求较苛刻的情况下,系统可以保证超调更小、响应更快、抗干扰能力强。并基于变论域模糊PID算法设计一个模糊PID控制器。最后对整个系统在Matlab环境下进行仿真实验,对比一般模糊PID控制和变论域模糊PID控制的动、静态性能,从实验角度深入分析验证变论域模糊PID控制具有更佳的性能参数和控制效果。
As the controlled object is hi-temp Muffle resistance furnace,the paper mainly discusses how to combine variable universe algorithm and fuzzy-PID control algorithm in the temperature-rise period of Hi-temp Muffle resistance furnace to achieve variable universe fuzzy-PID control.The variable universe fuzzy-PID control can ensure the faster response,less overshoot and better ability of anti-jamming in the harsh temperature environment.In the end,it designs a variable universe fuzzy-PID controller which based on variable universe fuzzy-PID algorithm and simulates the whole system in the Simulink environment on Matlab,compares variable universe fuzzy-PID with fuzzy-PID,the simulation experiment proves the variable universe fuzzy-PID has better performance parameter and control effect.
