Aiming at the problems of difficult setting,poor stability and unsatisfactory synchronization effect of traditional PID algorithm in hydraulic synchronization system,a double cylinder coupling synchronization control strategy based on fuzzy single neuron PID compound algorithm was proposed to improve the performance of synchronization system.The mathematical model of the proportional valve controlled asymmetric cylinder synchronization system was established.Simulink software was used to compare and analyze the control effect of traditional PID algorithm,single neuron PID algorithm and fuzzy single neuron PID algorithm.The system synchronization performance under the three control strategies was verified by experiments.The experimental results show that using the fuzzy single neuron PID coupling control strategy,the synchronization error of the system can be significantly reduced,and the response speed is faster.The designed control strategy is effective.
