Overhead crane control system based on improved dual-loop fuzzy PID control algorithm
To address the issue of load swing and crane positioning during lifting operations of cranes,an im-proved dual-loop fuzzy PID control algorithm is proposed.The mathematical model for the industrial crane anti-swing and crane positioning control system is established using the Lagrangian equation.This algorithm is ap-plied to the constructed model,and PID control systems,fuzzy PID control systems,and an improved dual-loop fuzzy PID control system are designed on the Simulink simulation platform for comparative experiments.Simulation results indicate that the improved dual-loop fuzzy PID control system exhibits a 32.6%and 16.5%increase in suppression capability for swing angles in comparison with the PID control system and fuzzy PID control system,respectively.The adjustment time for the position of the trolley is reduced by 5.442 s and 2.743 s,respectively,with no overshoot.The improved dual-loop fuzzy PID control system demonstrates better accuracy and stability,meeting the control requirements of the bridge crane system more effectively.
