Research on Dual Loop Control Algorithm Based on Pressure and Temperature in Wing Anti-Icing System

In wing anti-icing system, a common method employs heated air to control the opening of the anti-icing valve based on pressure. However, system delays may cause excessive wing temperatures. This paper proposes a dual-loop control model based on pressure and temperature for the anti-icing valve. The model simulates anti-icing performance under specified conditions. Results indicate that the dual-loop control model not only allows the system to quickly reach the anti-icing temperature but also maintains a stable temperature, addressing the issue of excessive heating on the wing skin. This approach shows promising application potential in wing anti-icing system.
