In this paper, the problem of H∞ filtering for networked singular systems with an event-triggered scheme is investigated. With a modified event generator, remote sensor evaluates the periodically sampled data and only transmits those violate a certain event-triggered condition, and thus reduces the communication burden. The filtering error system is converted into a time-delay system model which can...
To deal with the difficulty of establishing the accurate dynamics mathematical model of the underwater robots, a qualitative modeling method of underwater robots dynamics is presented based on qualitative simulation. Considering the complexity of the working environment and particularity of the non-linear movement process of underwater robots, through determining the landmark values and distinguished...
As the impact of underwater vehicle dynamics modeling error on fault diagnosis system, a method using improved Elman neural network to modify underwater vehicle dynamics model in the current is proposed. The neural network parameter adjustment law under the Lyapunov stability is given. Sliding mode observer is constructed for state estimation based on the modified dynamics model. The change of state...
