中文摘要:
      针对桥式吊车滑模控制器参数设置繁琐以及布谷鸟搜索算法(Cuckoo Search,CS)全局搜索能力不足问题,提出了自适应选取交叉操作算子的布谷鸟搜索算法(Cuckoo Search Algorithm with Adaptively Selecting Crossover Points,ASCP-CS),并将该算法用于桥式吊车滑模控制器参数整定. 该算法在CS算法的基础上改进自适应搜索步长,并在交叉操作过程中引入自适应选取染色体交叉点. 通过对4种典型寻优函数进行测试的结果表明:ASCP-CS算法具有较好的寻优精度和搜索能力. 对桥式吊车滑模控制器采用不同优化算法进行参数整定,仿真实验表明,基于该算法的控制器能更快地实现吊车负载定位,更有效抑制负载摆角,并具有较好的鲁棒性.
英文摘要:
      For the tedious parameter settings of sliding mode controller of bridge crane and insufficient global searching ability of Cuckoo Search(CS),an improved Cuckoo Search algorithm based on adaptive crossover operation point selection(ASCP-CS) was proposed and applied to the adjustment of parameters for the sliding mode controllor of bridge crane. The ASCP-CS algorithm improves the adaptive searching steps based on the CS algorithm, and introduces the adaptive selecting chromosome crossover points in the crossover operation. The test results of four typical optimization functions show that ASCP-CS algorithm has better optimization accuracy and search ability. The sliding mode controller of bridge crane is tuned by different optimization algorithms. It is showed in the simulation results that the controller based on ASCP-CS algorithm can locate the payload more quickly, suppress the swing of the payload more effectively and has strong robustness.
