This paper presents a backstepping procedure to design an adaptive controller for the air-breathing hypersonic flight vehicle (AHFV) subject to external disturbances and actuator saturations. In each step, a sliding mode exact disturbance observer (SMEDO) is exploited to exactly estimate the lumped disturbance in finite time. Specific dynamics are introduced to handle the possible actuator saturations...
Considering multiple-packet transmission and data packet dropout in both sensor-to-controller and controller-to-actuator cases in networked control systems (NCSs), we present a method to exponentially stabilize the NCSs. For multiple-packet transmission, a more general result is derived, and the algorithm to solve the static feedback controller is given. A numerical example is given to illustrate...
The problem of delay-dependent robust passivity analysis and robust passification for uncertain Markovian jump linear systems (MJLs) with time-varying delay is discussed. The parameter uncertainties are time-varying but norm-bounded. Attention is focused on the design of passification controllers, which guarantee that the closed-loop MJLs is passive. By constructing a proper stochastic Lyapunov-Krasovskii...
This Letter investigates the function projective synchronization of different chaotic systems with unknown parameters. By Lyapunov stability theory, the adaptive control law and the parameter update law are derived to make the states of two different chaotic systems asymptotically synchronized up to a desired scaling function. Numerical simulations on Lorenz system and Newton–Leipnik system are presented...
This paper discuses the tracking control problem of free-floating space robot in Cartesian space. Based on the augmentation dynamic equation, a robust controller is proposed considering the model uncertainties and external disturbances, using Lyapunov direct method and dissipative theory, it is proved that the proposed controller can ensure the L2 gain from disturbance to tracking error is lower than...
