AI Technical Summary
Existing technologies cannot effectively solve the problems of dead zone, nonlinearity, actuator saturation and parameter sensitivity of electro-hydraulic proportional multi-way valves, resulting in insufficient control accuracy and dynamic response performance.
A multi-valve collaborative control method based on group optimization and anti-saturation is adopted. Through the deep integration of the global optimization layer, dynamic compensation layer and logic driving layer, the PID gain parameters and anti-saturation gain parameters are integrated to achieve parameter collaborative optimization and dynamic compensation, reduce integral saturation, and improve control accuracy and dynamic response.
It achieves high-precision, fast-response, and robust control, significantly reducing steady-state error and overshoot, and improving the system's anti-saturation capability and robustness.
