柴油机模糊自校正PID控制器

Self tuning PID controller of diesel engine based on fuzzy logic

提出一种在线修正 PID参数的模糊控制器改进算法 .首次增加载荷和增压器进气流量作为新的模糊变量 ,用模糊芯片 F10 0实时调整柴油机电子调速器 PID参数 .仿真结果和 Z613 5柴油机调速性能试验表明 ,模糊控制器改善了调速器带载条件下的动态响应 。

An improved fuzzy logical algorithm is proposed which is suitable for self tuning parameters online in PID controller. The fuzzy inference mechanism is carried out by the fuzzy control chip F100, load and flux of air are treated as controlling parameters in diesel engine fuzzy controller by using F100 for the first time. The simulation results show that the on line fuzzy logic regulator of PID parameters used in PID controller has expanded the range of dynamic response of the controller in the case of loads. The overall characteristics of the control system are improved obviously in the experiment on diesel engine type Z6135.
