摘　　要：针对电加热炉温度控制系统,研究了Smith Fuzzy-PID控制方法。该控制器同时兼顾了模糊PID控制器和Smith预估器的优点,既可以整定参数,又使控制器提前动作,减少超调。Matlab仿真显示,该控制器具有良好的稳定性和鲁棒性,控制效果明显好于PID控制效果。实际运行结果也表明,对于大时间滞后的电阻炉温控系统是一种实用而简便的控制方法。Based on the temperature control system of electric resistance furnace,a method was studied on Smith Fuzzy-PID control.The control takes the advantages on the parameters adjusting of fuzzy PID controller and the advantages on estimation of smith-predictor in advance with low overshoot.Simulation results by Matlab shows that the controller is better than PID controller in respect of control effect with good stability adaptability and robustness.The practical results show that it is an appropriate and simple control method for the system with pure time delay.
