Fuzzy-model-based finite-time control of nonlinear spacecrafts over a distributed sensor network

In this paper, the problem of finite time control on a nonlinear flexible spacecraft system with random faults is addressed. In practical sensor sampling, the signal in the form of a single packet transmission maybe occur some phenomenon, such as data packet loss, random failure. The actuator failures are considered as random signal obeying Markov process. To overcome the difficulty, a finite time fuzzy control scheme is proposed based on a distributed sensor network. Based on the Lyapunov stability theorem, a design method of controllers is given and a stability criterion with satisfying H_∞ performance is obtained in mean-square sense. In the end, a numerical example of the nonlinear spacecraft is used to illustrate the effectiveness of the obtained results.
