摘要
在原动机仿真系统中,关于其速度电流综合调节器(实质为PI调节器)的参数一直以来都是依靠传统方法来确定的,这种方法不但耗费较多的时间,而且很难寻求到一组理想的参数。将遗传算法引入便可很好地解决这些问题,通过具体的实例,运用Matlab仿真试验,在遗传算法和传统方法条件下,进行了调节器阶跃响应特性的比较,试验结果证明,遗传算法具有快速确定和优化PI参数、且原动机仿真系统动态特性好的显著优点。
In the prime mover simulation system, the parameters of the PI regulator are always confirmed in traditional method, but this method consume much time and is hard to get ideal parameters. Genetic algorithms will smoothly solve these problems. By an example, simulating with MATLAB between the additional method and genetic algorithm,it compares the step response characteristic, the result proves that genetic algorithm can fix the PI parameters quickly, and enable the prime mover simulation system have a better dynamic characteristic.
