摘要
针对电加热炉的数学模型具有非线性、大惯性、线滞后以及时变等特点,应用免疫反馈系统的原理和模糊控制理论,在传统PID控制的基础上设计出一种模糊免疫自适应PID控制器,并对某工业电炉的控制系统进行了动态仿真。仿真和实际运行结果表明,该控制器具有使系统超调量小、调整时间短、鲁棒性好且算法简单等优点,是一种提高电加热炉温度控制效果的有效方法。
The characteristics of temperature＇s control of resistance-heated furnace are nonlinear, strong inertia, time-variant, and pure delay. A kind of fuzzy immunity adaptive PID controller was designed by combining the principle of immune feedback system and the theory of fuzzy controlling, based on the traditional PID control, and the dynamic imitation of the control of the re- sistance-heated furnace was processed. The simulation researches and practical results show the system with the controller has properties of no overshoot, quick response, good robust and the algorithm is simple. It is proved that this control algorithm is a more effective one on improving the temperature＇ s control of the resistance-heated furnace.
