Adaptive Backstepping Based Fault Tolerant Spacecraft Attitude Control Under Loss of Actuator Effectiveness
In this paper, an adaptive backstepping technique based fault tolerant control scheme is developed for a spacecraft attitude stabilization system, in which the external disturbances and partial loss of actuator effectiveness fault are considered. More specifically, using the adaptive backstepping control method, a baseline control law is first proposed for the normal system without actuator fau...
متن کاملActive fault-tolerant attitude control for flexible spacecraft with loss of actuator effectiveness
A theoretical framework for active fault-tolerant attitude stabilization control is developed and applied to flexible spacecraft. The proposed scheme solves a difficult problem of fault-tolerant controller design in the presence of severe partial loss of actuator effectiveness faults and external disturbances. This is accomplished by developing an observer-based fault detection and diagnosis me...
متن کاملAdaptive Fault-tolerant H∞ Compensation Controller Design with Actuator Failures
In this paper, the problem of designing adaptive fault-tolerant H∞ compensation controllers for linear timeinvariant continuous-time systems is presented. Linear matrix inequalities (LMIs) are developed with multiple Lyapunov functions to find a stabilizing controller gain such that the disturbance attenuation performance is optimized. Direct adaptivestate feedback control schemes are proposed ...
متن کاملAdaptive Spacecraft Attitude Tracking Control with Actuator Uncertainties
An adaptive control algorithm for the spacecraft attitude tracking problem when the spin axis directions and/or the gains of the flywheel actuators are uncertain is developed. A smooth projection algorithm is applied to keep the parameter estimates inside a singularityfree region and avoid parameter bursting. Numerical examples show that the controller successfully deals with unknown misalignme...
متن کاملFault-Tolerant Attitude Control for Flexible Spacecraft with Input Saturation
Fault-tolerant constrained attitude controllers are proposed for flexible spacecraft in the presence of input saturation and actuator fault, as well as model uncertainty and external disturbance. Two input saturations, that is amplitude saturation and, amplitude and rate saturation are considered and simple and effective compensators are designed to deal with the effect of input saturation. Two...
