RCS Control Study Based on the Model Reference Adaptive Control

摘要

For the reusable launch vehicle(RLV),in the cruise stage without power and the initial load phase,due to the aerodynamic pressure is small,and the aerodynamic surface control efficiency is relatively low,it can not achieve the attitude adjustment of the RLV.This design is based on the continuous system,and applies to the model reference adaptive control law algorithms,to achieve the design of the reaction control system(RCS).According to the control torque which is required by the RLV attitude adjustment,the RCS distribution method of mixed-integer programming is used,and the control parameters of the reaction control system is adjusted in real time,thus to achieve the adjustment of the RLV's attitude.Through the software-digital simulation analysis,this method has a good controllability and robustness.At the same time,the stability of the model reference adaptive RCS is analyzed theoretically,and getting a certain amount of stability region.
