基于蚁群算法PID控制器的应用研究

摘要

传统的PID控制对于控制模型不确定并具有非线性特性的对象时,存在参数难以整定、控制效果不好的缺点,文中提出了一种基于蚁群算法的PID调节算法,即利用蚁群算法动态调节PID的参数,实现对配料系统的控制,通过实验仿真的方式证明了该方法具有良好的控制效果及适应性。%In response to the defect of uncontrollable parameter and low precision problem with old fashion PID proportioning system,when the mathematical mode of controlled plant with nonlinear behavior 1 is determinate , this paper puts forward a PID parameter optimal control way based on ant colony algorithm,that dynamically regulate and control parameter of pid,The smiulation results show the satisfied performances and Strong adaptability of the proposedmethod.
