Hierarchical Multiple Models Adaptive Controller Applied to the Non-Minimum Phase Wind Tunnel System
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 responses requirements are high. To deal with these problems, a Hierarchical Multiple Models Adaptive Controller (HMMAC) 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. Adaptive Controller is designed to control the multivariable non-minimum phase system. The significance of the proposed method is that it is applicable to a MIMO non-minimum phase system with a much small number of models. The global convergence is obtained. Finally, several simulation examples in a wind tunnel experiment are given to show both effectiveness and practicality of the proposed method.
