Abstract: The electro-hydraulic proportional position servo system is a kind of highly
non-linear and time-varying system as well as parameter uncertainties. It is often difficult to
achieve satisfactory control results with the traditional control methods. Considering that the
adaptive neural network PID control method has the characteristics of online learning and
adjustment PID control parameters adaptively, this paper puts forward to adopt BP-PID control
method for the position servo control of electro-hydraulic proportional system. An online
adaptive BP-PID controller is designed. The simulation model of the system is established based
on Simulink platform. The step response and Sinusoidal tracking characteristics are researched
through simulations and experiments. The results show that BP-PID has a strong ability of online
learning and self-tuning PID parameters. Compared with the traditional PID control method, the
BP-PID control has strong self-adaptability and robustness, and can significantly improve the step
response speed and tracking control precision.
