DNN Control Optimization of EPS Servo Variable Amplitude Loading System PID Establishment
In order to further improve the motion accuracy of electro-hydraulic servo loading system of electric power steering,a PID control system was designed to establish DNN control system.The electro-hydraulic position servo system is constructed by the mode of flexible connection to ensure the rapid dynamic control in the transient equilibrium response.The flexible electro-hy-draulic position servo control test was built and the control effect was analyzed.The research results show that the DNN controller established by PID plays a key role in the correction of electro-hydraulic position servo parameters of flexible coupling,and the overall response time is greatly shortened,ensuring that the dynamic control effect of the system frequency band is significantly improved.When DNN controller is used to adjust the electro-hydraulic servo system of flexible connection,the low-frequency load displacement accuracy of the system can be effectively enhanced,the problem of amplitude attenuation can be avoided,and the electro-hydraulic position servo parameters of flexible connection can be tracked with higher accuracy,which promotes the obvi-ous improvement of the tracking performance of the system.This research has a good theoretical support for improving the stability of vehicle operation and energy saving.
