摘　　要：在输入和扰动共同作用下,提出了基于粒子群优化(PSO)算法的最少拍控制器的自动设计方法。基于扰动作用下最少拍控制器的设计理论构建修正等式,然后根据等式两边对应项系数相等以建立适应度函数,进而应用粒子群优化算法求解修正等式中的未知数,以实现最少拍控制器的自动化设计。实例仿真发现,应用该算法和手工计算的结果一致,验证了该方法的可行性和准确性。研究结果为最少拍控制器的教学和工程应用提供了一种计算机辅助设计工具。The aim is to propose an method for automatic design of disturbance rejection deadbeat controller based on PSO（particle swarm optimization）.Firstly,an equation,which contains unknown variables to be determined,was developed to modify deadbeat controller for improvement of disturbance rejection according to the design theory of deadbeat controller.Secondly,the fitness function was created,as coefficient of the lefthand side term with the same power should be equal to that of the right-hand side term for the developed equation.Thirdly,the unknown variables were determined automatically using particle swarm optimization without any manual intervention.Finally,simulations demonstrate that the results from the presented method are equal to those from manual design,which verifies the feasibility and effectively of the presented method.This work offers a valuable CAD tool,and it facilitates the teaching,experiment and practical application of deadbeat controller.
