AI Technical Summary
Existing pulse-type solenoid valve water flow control methods are unstable when facing complex environments with frequent water pressure fluctuations, resulting in flow oscillations and reduced control accuracy, especially in building water supply systems.
A fuzzy controller is used in conjunction with a correction mechanism that combines timing boundary sensitivity and smoothing weight coefficients to dynamically identify whether the system is in a high-risk region of the fuzzy set boundary. The pulse duty cycle reference value is adaptively adjusted to generate a smoothed pulse duty cycle value. The continuity and safety of control are ensured by single-step change constraints.
It effectively avoids the output jump problem in the boundary region of traditional fuzzy controllers, ensures continuous and stable control of water flow, improves control accuracy and system stability, and prevents water hammer effect and flow shock.
