摘要
以某型船用柴油机为对象,建立了柴油机控制系统的简化传递函数和执行器模型。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仿真分析,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,对柴油机控制调速系统的性能有很大提高。
The genetic algorithm is an arithmetic, which is simulating the biology and random sample to optimize. The article aims at a kind of the diesel and establishes the model of the control system and the model of the executor. Using the control of PID, the parameters of the controller are optimized by the genetic algorithm. The simulation analysis is done for the speed control process of the diesel engine, which is compared with the parameter setting method based on Z-N method. The results show that the genetic algorithm is far better than the traditional parameter setting method, which has effectively improve the capability of the speed control system of ship diesel engine.
