The QiTai Radio Telescope (QTT) will be equipped with the active surface adjustment system (ASAS) to correct the main reflector deformation caused by environmental loading. In order to guarantee the stability and performance of the active surface system under fault conditions, it is necessary to adopt the fault-tolerant method when actuator faults have occurred. In this paper, a fault control method based on actuator faults weighting is proposed to solve the active surface fault control problem. According to the coordinates of the adjustable points of the panels corresponding to the faulty actuators, a new paraboloid is fitted by a weighted health matrix, and the fitting surface is taken as the target to adjust the surface shape.

带有执行器故障的主动表面系统的容错

奇台射电望远镜（QTT）将配备主动表面调整系统（ASAS），以纠正由环境负荷引起的主反射镜变形。为了保证故障条件下活动表面系统的稳定性和性能，当执行器发生故障时，有必要采用容错方法。提出了一种基于执行器故障加权的故障控制方法，以解决主动面故障控制问题。根据与故障致动器相对应的面板的可调节点的坐标，通过加权健康矩阵拟合新的抛物面，并以适配面为目标来调整表面形状。
