Firstly, an observer-based fault diagnosis method is proposed to estimate the marking with unknown initial markings and meanwhile, to diagnose the faulty behavior.
The control problem is solved in two consecutive steps: firstly, designing an observer based on the measured output and, secondly, designing of a full-state controller computed from a new virtual output with vector relative degree.
Firstly, an effective observer is designed to identify the unknown parameter of Lü system, then the backstepping method is applied to control the uncertain Lü system to bounded points.
Firstly, a backstepping observer is designed.
Firstly, a functional observer is designed for the attitude systems of flexible spacecraft in order to detect the time of unknown sensor fault occurred.
Firstly a modular observer is proposed to estimate the vehicle longitudinal velocity, and input-to-state stability theory is utilized to prove that the estimation error converges to zero.
Firstly we designed an observer to identify the unknown parameter of Lü system, then we used backstepping design method to control the system, and track any desired trajectory by the same way.
Firstly, a singular observer-type synchronization protocol is introduced, where the errors of protocol states among neighboring agents are applied to make complex networks satisfy a specific separation principle which can simplify synchronization analysis and design problems.
To achieve these control strategies, firstly, a state asymptotic observer and a robust interval observer for a class of bioprocesses are presented.
Firstly, a high-gain observer (HGO) is used to estimate the joint velocities.
