摘要
以12V180柴油机为对象,建立了柴油机简化传递函数和执行器模型。控制方法采用PID控制,并利用遗传算法优化控制器参数,对柴油机动态调速过程进行了仿真分析,在30s和60s时分别突加和突减50％负荷,并列出了柴油机各参数在负荷突变时的仿真结果。仿真结果和基于Z-N(Ziegler-Nichols)法的参数整定方法做了比较,结果表明遗传算法的性能远优于传统的参数整定法。
Transfer function and controller models are established for 12V180 diesel engine. Traditional PID algorithm is adopted. Simulation analysis on dynamic regulating process of governing system for diesel engine is made ,and the parameters of PID controller are optimized by Genetic Algorithm. 50% load is added at 30s and 60s ,and simulation results of parameters when load is abruptly changed are listed. Simulation result is compared with Zigler - Nichols method .and the result indicates that the characteristic of GA is far better than that of Z - N method.
