针对垂直起降火箭(VTVL)返回段的容错控制问题,设计了自适应的快速故障检测与可重构控制算法。它由一个基本控制器、执行器动力学模块、可重构控制器和一个离散化的故障检测(FDI)模块构成,能够应对单个或多个执行器卡死或失效故障。针对火箭返回段弹道设计了参考模型并对垂直起降火箭的动力学模型进行了建模。在单个或多个执行器卡死或失效故障条件下的仿真结果表明,该算法能够快速进行故障检测并进行可重构控制。 Aiming at the fault-tolerant control problem of VTVL return section, an adaptive fast fault detection and reconfigurable control algorithm is designed. It consists of a basic controller, actuator dynamics module, reconfigurable controller and a discretized FDI module that can handle single or multiple actuators stuck or malfunctioning. A reference model is designed for the rocket’s return trajectory and the dynamics model of the vertical take-off and landing rocket is modeled. The simulation results under single or multiple actuators stuck or failure conditions show that the algorithm can quickly detect faults and reconfigurable control.
