Modeling and Improved Switching Control of Hypersonic Vehicle with Uncertainties

Abstract

In order to achieve an effective control approach for hypersonic vehicle over a wide flight envelope with uncertainties of structural dynamics and system parameters, a unified modeling and improved switching controller design approach is proposed, and the Adams Customized Development Platform of Flight (ACDPF) has been developed to implement it. The paper firstly discusses the main issues related to the model of the ACDPF, which can be set parameters by several blocks. And it also supports the reuse of modeling among similar missions, thus cutting down the design effort for new model. Then, the improved switching control with baseline controllers and robust adaptive controllers are selected in order to adjust control law to compensate for uncertainty. Finally, the effectiveness of the proposed approach is demonstrated by illustrative case studies and simulation results show that the approach provides a well tracking performance.
