摘　　要：研究电机绝缘处理的过程中,针对烘干炉的温度控制具有非线性和大滞后的特点,常规的PID控制器和模糊控制器很难达到理想的控制效果,为保证温度系统的稳定性,把模糊控制和常规的PID控制结合起来,提出了模糊自适应PID控制器。首先建立了烘干炉温度控制系统的数学模型,确定了系统的输入输出量,建立了模糊控制规则,进行模糊推理,计算PID控制器的参数,可由PID控制器控制烘干炉的温度,采用计算机仿真结果表明,模糊自适应PID控制器与常规PID控制器相比较,提高了烘干炉温度控制系统的自适应能力和鲁棒性,改善了系统的动态性能和静态性能,能使非线性、大滞后等特殊的系统达到良好的控制效果。The tempreature control of the drying oven has such proplems as nonlinearity and time delay during the process of electric engine insulation.Neither a general PID controller nor fuzzy controller can achieve a satisfactory effect.To resolve the problem,a fuzzy PID Controller is designed to combine the advantages of PID control and fuzzy control.First,a mathematical model of the temperature control system of the drying oven is built.Next,the input-output volume of the system is established before setting fuzzy control rules to make fuzzy reasoning.The parameters of the PID Controller are then figured out,which enables the PID Controller to be finally used to control the temprature of the oven.The computer emulation result as well as the spot test shows that the fuzzy self-tuning PID controller,compared with the traditional PID controller,can increase the self-tuning ability and the robustness of the temperature control system.It can improve both the dynamic and static property of the system,hence a better effect for special systems like nonlinear or time-lag ones.
