AI Technical Summary
Existing laboratory differential pressure control systems have poor anti-interference capabilities and slow response speed when facing dynamic changes, and also pose safety risks and energy waste.
An adaptive control method for ventilation pressure difference in laboratory rooms is adopted. A basic parameter library of the system is established through initialization processing, real-time multi-source data is collected, and a two-stage adjustment is performed using a self-learning model and PID algorithm. Combined with iterative control, the system can quickly identify and accurately adjust wind pressure difference interference.
It significantly shortens the differential pressure fluctuation range and recovery time, improves the system's anti-interference capability, ensures that the differential pressure remains stable within the target range under any operating conditions, and improves the system's reliability and stability.
