| 摘 要： | 针对挠性航天器执行器卡死与失效故障的姿态稳定控制问题,提出一种改进型滑模容错控制策略.与传统的滑模控制相比,该方法能削弱传统滑模控制中抖振现象对姿态控制精度的影响,且它采用自适应技术在线估计系统中的不确定参数,从而保证控制性能对外部干扰、不确定甚至时变转动惯量具有良好的鲁棒性.该控制器并不需要任何在线或离线的故障信息,...

| Abstract: | A modified sliding mode fault tolerant controller is developed for flexible spacecraft attitude stabilization control with consideration of loss of actuator effectiveness fault and actuator stuck fault.In contrast to the traditional sliding mode control,the proposed control law can avoid the chattering effect that may affect the resolution of attitude control.System uncertainties are estimated on-line by using an adaptive technique to guarantee that the proposed controller possess great robustness against e... |
