摘　　要：针对传统PID的整定存在的不足,引入CCA(Colonial Competitive Algorithm),该算法是一种属于社会启发的算法,以被控对象的二次型性能指标优劣作为PID整定的衡量标准,提出了一种新的PID整定方法,该算法可以在搜索空间里迅速收敛到最优解。由仿真结果说明,该整定算法节省内存,寻优时间短且不需要设置初始的PID参数,具有比采用遗传算法等优化算法整定的效果好等优点。Contrary to the shortcomings of conventional PID tuning method, Colonial Competitive algorithm was introduced, which belongs to Community-inspired algorithms, quadratic performance index of controlled object is introduced as a criteria of performance of tuned PID controller, a new PID tuning method was proposed. This method can quality converge to the optimal solution in the search space. Simulation results showed that this method could save computer memory, less time consuming and PID initial parameters did not need to set, the optimal solution obtained by CCA was better than other optimal algorithms such as genetic algorithm.
