This article develops a multiple-model-based adaptive control scheme to compensate for actuation sign faults of the flexible spacecraft using an error transformation. Multiple control signals are designed based on multiple estimators and an error transformation among estimation errors, tracking errors of estimators, and a virtual control error. A switching mechanism is established using a group of cost functions to choose the most proper control signal that can guarantee the desired system stability and asymptotic tracking performance.

挠性航天器驱动信号故障的自适应补偿

本文开发了一种基于多模型的自适应控制方案，以利用误差变换来补偿挠性航天器的致动信号故障。基于多个估计器以及估计误差，估计器的跟踪误差和虚拟控制误差之间的误差变换来设计多个控制信号。使用一组成本函数来建立切换机制，以选择最合适的控制信号，以保证所需的系统稳定性和渐近跟踪性能。
