摘要
提出了一种具有多输入 /多输出 (MIMO)结构、在线修正 PID参数的柴油机模糊控制器和改进算法。在算法中建立了柴油机模糊 PID控制器的三维模糊数学模型 ,提出用载荷和增压器进气流量作为新的模糊控制变量 ,并用模糊控制芯片 F10 0实现了实时在线调整柴油机电子调速器 PID参数。仿真结果和 Z6 135柴油机调速性能试验表明 ,使用模糊智能控制器可以改善调速器在柴油机带载条件下的动态响应。
WT5”BZ] An improved fuzzy logical algorithm suitable for self tuning of parameters is proposed on line in PID controller.A 3D fuzzy model is established in PID controller of diesel engines and the fuzzy inference mechanism is performed by the fuzzy control chip—F100.The load and flux of air are initially treated as controlling parameters in diesel engine fuzzy controller by using of the F100.The process simulation and test measurement show that the on line fuzzy logic regulator of PID parameters in the PID controller has expanded the dynamic response range for the controller in the case of loads.The overall characteristics of the control system have been improved obviously on the Diesel engine type Z6135.
