The BTT Control System Design for Re-entry Warhead Based on the Theory of Adaptive Variable Structure

Using the traditional method of variable structure control to design the BTT control system of re-entry warhead,there exists the serious chattering phenomenon.Besides,it is difficult to analyze the sliding mode stability by using the conventional switch function design method,when there are unmatched uncertainties.In view of that,the design of the adaptive variable structure controller has less conservative stability conditions for the sliding mode by using the dynamic compensator.The simulation results show that the BTT control system based on the theory of adaptive variable structure control can fulfill the BTT control system requirements.
