This paper deals with the problem of fault-tolerant control (FTC) for flexible spacecraft with partial loss of actuator effectiveness and time-varying input delay. An adaptive fault-tolerant controller is designed by using the online estimation, in which an addition control term is added into the normal control law. This compensation method can reduce the fault effect and don't need the isolation...
In this paper, we design a fuzzy fault-tolerant tracking controller for the Mars Entry Vehicle (MEV) with the partial failure of actuator, external disturbance and input delays. Firstly, we divide the attitude system of MEV into slow subsystem and fast subsystem. By using the slow subsystem, we can get angular velocity and then choose this angular velocity as the reference angular velocity for the...
This paper investigates the fault-tolerant shape control (FTSC) problem for stochastic distribution systems. For this problem, in addition to measurable input signals, it is assumed that the distribution function of the system output can be evaluated so that it is available. It is also assumed that the system is subject to actuator faults. In this case, the main control objective is for the output...
This paper investigates the fault-tolerant shape control (FTSC) problem for stochastic distribution systems. The available information for the addressed problem is the input and the measurable output Probability Density Function (PDF) of the system. The system is subject to actuator faults. In this case, the main objective is to achieve fault-tolerant shape control so that the output PDF can track...
