Research On Synchronous Control Of Double Hoist Hoisting System Of Crane

The mobile harbor crane is one of the main equipment for port operation,and its importance of quality is beyond doubt.As the key component system of the crane,the operation synchronization of the double winch system directly affects the safety of the crane operation.However,although the existing synchronization control strategy is simple and easy to achieve,it ignores the influence of many intermediate factors,and the actual synchronization control effect is not reasonable.Therefore,this paper makes an improvement study.First of all,based on the principle of dual winch system,this paper constructs the mathematical model and Simulink simulation model of the system,and studies the performance of the existing dual winch system from multiple perspectives,and finds that the existing system has good stability,but the dynamic response speed is slow.Then,this paper studies several common synchronous control methods and control algorithms,and specifically analyzes the control effect of the existing synchronous control strategy.Based on the working characteristics of the dual winch system,an improved fuzzy self-tuning PID control strategy with hook angle as feedback is proposed.After that,this paper designs the fuzzy controller of the double winch system step by step,and the system simulation model based on the improved control strategy is built in Matlab/Simulink.By comparing the simulation control effect of the original and improved control strategies under different working conditions,it is proved that the improved strategy has better effect in the regulation efficiency,regulation accuracy and stability.Finally,this paper studies the realization of the hook angle signal acquisition module,designs its hardware circuit and software,and tests the feasibility of the design through experiments;at the same time,it studies the realization method of the fuzzy PID control algorithm in the synchronous controller PLC,and proposes to establish the correspondence between the fuzzy input and the real output by constructing the fuzzy query table,the corresponding STL program is given.The improved control strategy proposed in this paper can ensure the synchronous operation of the system more effectively,and the relevant research content can provide reference for the design of the dual winch controller.
