针对空天飞行器再入段异构执行机构复合控制问题,基于气动舵面和反作用推力器的特性,提出了适用于空天飞行器的3种气动舵面与反作用控制系统的复合控制构型:指令型、力矩型、指令误差型,以及相应的控制律设计方法,在此基础上完成空天飞行器再入段的控制系统设计。仿真结果表明,3种构型的复合控制系统均能满足指令跟踪性能要求,其中指令型复合控制系统气动舵工作最为平稳,推力器开启频次最少。从工程应用的角度出发,指令型复合控制系统的综合性能最为理想。
Aiming at the complex control problem of aero-engine reentry reactor, based on the characteristics of aerodynamic rudder and reaction thruster, three kinds of composite control configurations of aerodynamic rudder and reaction control system are proposed for aerospace vehicle: command type, Torque type, command error type, and corresponding control law design method, based on which the control system design of aerospace vehicle reentry section is completed. The simulation results show that all the three kinds of hybrid control systems can meet the requirements of command tracking performance. Among them, the command type composite control system has the most stable aerodynamic rudder and the least thrusters. From the engineering point of view, the comprehensive performance of the command type composite control system is the most ideal.
