A new approach of anti-swing control system based on run-to-run control and fuzzy control for overhead crane

摘要

Bridge cranes at work, due to the large, car plus (minus) speed and improve load factors, will cause the load to swing. This not only increases the likelihood of accidents, but also will seriously affect the efficiency of the production. Under the prerequisite of ensuring the crane operating efficiency, to prevent the swinging of load for bridge crane has great meaning. Based on the physical characteristics of bridge crane inSimulinkestablished with inverter, motor and crane model. According to simulations a mathematical model is proposed based on fuzzy control and batch control of overhead traveling crane anti-sway control method. In actual experiments, using load and the angle of tilt sensor the mass of load is measured as a feedback signal. And, ultimately, the crane's operating efficiency, angle control in the ideal range is ensured.
