AI Technical Summary
Existing electronically controlled pressure regulating valves cannot achieve rapid and stable pressure control in engine exhaust gas bypass control systems and automotive braking systems, especially when the pressure chamber volume changes.
A combination of dynamic and steady-state control strategies is adopted. The opening of the pressure regulating valve is controlled by adjusting the current of the proportional valve. The dynamic control strategy is used to quickly reach the desired pressure, while the steady-state control strategy is used to maintain pressure stability. The combination of multiple control strategies can adapt to pressure chambers of different volumes.
It enables rapid and stable adjustment of the pressure of the pressure regulating valve, improves the control applicability and stability of the pressure regulating device, and adapts to the needs of pressure chambers of different volumes.
