AI Technical Summary

Technical Problem

Existing hydraulic wind-driven reverse osmosis seawater desalination systems struggle to achieve precise energy matching and dynamic tracking when faced with wind speed fluctuations, resulting in low water production efficiency and unstable operation. Traditional linear control methods lack robustness and are prone to planning lag and state instability.

Method used

A control method based on two-layer collaborative optimization is adopted, including upper-layer dynamic target planning and lower-layer double-step sliding mode tracking, to construct a robust target setting trajectory. Combined with a dynamic correction mechanism of equivalent energy parameters, the system operating point is actively adjusted to improve wind energy utilization and water production stability.

Benefits of technology

It effectively solves the problem of energy matching and dynamic tracking of wind power seawater desalination modules under random wind speeds, improves wind energy utilization and water production stability, avoids the system from entering dangerous operating conditions due to wind speed fluctuations, and extends the service life of high-pressure pipelines, motors and reverse osmosis membrane components.
