Abstract

For the biggest wind tunnel in Asia, during the aerodynamic research on the scale models, it is difficult to keep the Mach number in the test section and the stagnation pressure constant strictly because the interaction is strong, the operation conditions change abruptly and the transient response's requirements are high. To cope with these problems, a Hierarchical Multiple Models Adaptive Decoupling Controller is presented in this paper. The controller is composed of multiple fixed controller models and two adaptive controller models. Multiple models are used to improve the transient response of the wind tunnel. Hierarchical structure is presented to reduce the number of the fixed models greatly. The significance of the proposed method is that it is applicable to a MIMO system with a much small number of models.The global convergence is obtained.
