摘　　要：矿热炉系统是一个非线性、强耦合、多变量的复杂系统。该文针对矿热炉电极控制这个随机干扰十分严重的非线性时变系统,设计了模糊自适应PID控制器。给出了Matlab仿真框图及阶跃响应的仿真曲线。试验结果表明,该控制器可以有效地调节电极的升降,将电弧的弧长控制在期望值,系统响应快、抗干扰能力强,可以有效地降低矿热炉的能耗。Submerged arc furnace system has a character of muhivariable,nonlinear and strong coupling. Considering submerged arc furnacc,a non-liner time-varying system with very strong random interference,a fuzzy adaptive PID controller is designed. Through Matlab simulation,it is proved that the system has fast response and strong anti-inter- ference capability. And the simulation results also show that the proposed controller can effectively regulate the rise and fall of the electrode and control the arc length at an expected value. It can be applied to reduce energy con- sumption.
