摘要
针对火电单元机组的多变量、时变和非线性特性,应用免疫反馈系统的原理和模糊控制理论设计了一个模糊免疫自适应PID控制器。对控制器中的比例系数kp采用免疫控制器调节,用模糊规则分别对ki,kd进行在线整定。结果表明,模糊免疫自适应PID控制器具有响应速度快、鲁棒性强等优点。
A kind of fuzzy immune self-adaptive PID controller is designed by combining the principle of an immune feedback system and the theory of fuzzy control for the multivariable, time-varying and nonlinear characteristics of a boiler-turbine coordinated control system in a thermal power station. The proportional gain kp is tuned by the immune controller, and ki, ka are tuned according to the fuzzy rule. Simulation results indicate that the fuzzy immune self-adaptive PID controller has advantages, such as short response and sufficient robustness.
