【摘要】 针对"并车"吊运100m钢轨时,要求两车的各运行机构严格同步,提出了一种基于PLC的复合模糊PID控制算法,其中模糊控制器和PI调节器都是通过PLC编程来实现,这样既保留了PLC控制系统灵活、可靠、抗干扰能力的特点,同时增强了控制系统的动态响应速度和智能化程度。实践结果表明:该系统同步控制精度高、适应性好、抗干扰能力强、鲁棒性好。更多还原

【Abstract】 For and cranes lifting 100m rail,two cranes of the operating agencies are strictly synchronized,a PID and Fuzzy combined control arithmetic based on PLC is presented.Both of the PID and Fuzzy controller are implemented by PLC,the presented method has the advantages of agility,trustiness,strong anti-disturbace disturber of PLC system,and improves the intelligence of the control system,while enhanc dynamic response speed and the intelligence of the control system.更多还原
