摘要
为实现桥式起重机在吊运中的稳定、高效、安全作业,针对起重作业过程中出现的定位不准和摆动剧烈等问题,笔者采用PID、FPID、SPSO+FPID等控制策略方法,对起重作业过程进行实际工况模拟,分析和评价各种控制策略在起重机的定位和抑摆的效果。研究结果表明,SPSO+FPID控制方法在快速消除吊重摆动的同时,可以有效实现小车的精准定位;与传统PID相比,SPSO+FPID控制方法的摆角减小了72.7%,定位超调量减小了20.0%,具有更好的鲁棒性,符合智能起重机的定位和抑摆要求,具有一定的工程实践指导意义。
In the hoisting of bridge cranes,in order to ensure its stable,efficient and safe operation,in view of the problems of inaccurate positioning and severe swinging during the lifting operation,the author adopts control strategy methods such as PID,FPID,SPSO+FPID,et al.The actual working conditions are simulated during the operation,and the effects of various control strategies on the positioning and sway suppression of the crane are analyzed and evaluated.Research indicates,SPSO+FPID control method can quickly eliminate hoist swing,and can effectively achievetrolley precise positioning;compared with the traditional PID,the swing angle of the SPSO+FPID control method is reduced by 72.7%,and the positioning overshoot is reduced by 20.0%.It has better robustness and meets the positioning and swing suppression requirements of intelligent cranes.It has certain guiding significance for engineering practice.
