摘　　要：针对加热器供气管路系统存在的非线性、时滞性、干扰性等特点,提出了一种基于非线性高斯函数的变参数PID控制算法。通过Matlab仿真实验,对传统PID与变参数PID的控制算法进行控制效果、克服滞后能力、抗干扰能力等方面的比较,证明了变参数PID控制算法的优越性。风洞实验结果也验证了变参数PID的控制效果。This paper design a PID controller with variable arguments based on nonlinear function of Gauss according to the nonlinearity, system delay and interference issue of the the control system of heat-er supply. The Matlab simulation results verify that the PID controller with variable arguments is better than the traditional PID controller for the control effect, time-delay compensation ability and anti-in-terference ability of the model identified before. The wind tunnel running results that the control effect of the PID controller with variable arguments is good.
