摘要：
To solve the problem that the hypersonic vehicle tracking control has challenges such as high control relative orders and strict process state constraints, the differential flatness-based hypersonic vehicle tracking control and outer loop tracking control method is proposed to avoid the robustness problems caused by control methods such as active disturbance rejection control (ADRC), while differential flattening maps the process state and control input into a function about the flattened output, which reduces the constraints dimensionality of trajectory planning while realizing the linearization of the model. For the attitude control inner loop with strong uncertainty. ADRC is used to avoid the differential explosion problem under the derivation of differential high order model, and ADRC does not depend on the exact model information, which improves the robustness of the control system. Simulation results show that differential flatness and ADRC' complement each other’s defects and have good control performance and robustness. © 2024 Chinese Institute of Electronics.
