【Abstract】 In order to improve the synchronization precision lifting precision of the double cylinders of fatigue testing machine, the single-neuron PID adaptive algorithm is used as a control strategy to overcome the problem of poor synchronous control effect caused by the difficult tuning of traditional PID parameters. Based on the analysis of the working principle of the synchronization system, the mathematical model is established, the control effects of the two control strategies is simulated. Finally, the synchronous lifting tests under different control strategies are carried out on the test machine. The experimental results show that the synchronization error rate of the single-neuron PID adaptive algorithm is 1.5%, and the error rate of the synchronization system under PID control is 3.75%, The single-neuron PID adaptive algorithm can effectively improve the synchronization accuracy of the two-cylinder synchronization system.更多还原
