摘要
水力发电机组是一个非线性、时变系统,常规PID控制不能达到理想的控制效果。提出一种基于改进蚁群算法的PID参数优化方法,讨论了蚁群算法的模型,水力发电机组的模型,对蚁群算法的不足进行改进,并给出了算法的具体实现步骤。实验结果表明,采用改进蚁群算法PID控制器的水电机组具有更好的控制精度和动态特性,验证了该方法的可靠性和有效性。
Hydropower generating units are a non-linear and time-varying system. Conventional PID control can＇t reach the ideal control results. This paper proposes a method for optimizing PID parameters based on the modified ant colony algorithm, discusses the ant colony algorithm model, the model of hydropower generating units, and gives the algorithm implementation steps. The experiment resuits show that hydropower generating units with modified ant colony algorithm and PID controllers have a better control accuracy and dynamic characteristics, which proves that the new method is reliable and effective.
