For a class of chaotic systems with uncertain nonlinear time-delay functions and exogenous disturbance, the problem of observer-based adaptive synchronization is investigated. Based on Lyapunov-Krasovskii fucntional method, a delay-free observer is presented by using sliding mode control and adaptive control techniques. Two numerical simulations are given to show the effectiveness of the proposed...
For the problem of the synchronization between two chaotic systems with external disturbances and nonlinear input, based on the Lyapunov's stability theory and combined the finite time principle with control technology existed, a sliding mode controller was designed by a new type of sliding surface and the corresponding control rule of sliding mode selectivity to achieve the synchronization control...
For a novel conveying mechanism which is highly nonlinear, highly time-varying and highly coupled, a synchronized sliding mode control with nonlinear disturbance observer is proposed to improve the synchronization performance and the disturbance-rejection performance. First, the kinematic analysis of the conveying mechanism is completed and the dynamic model with lumped disturbances of the conveying...
Microphone array for high-quality audio recording has been realized by dedicated devices. But lack of portability and high cost prevent such system being widely adopted. Today's commercial-off-the-shelf (COTS) smartphones are relatively more convenient for audio recording. However, in order to estimate the target's direction of arrival (DOA), several asynchronous receivers (smartphones) must be precisely...
Chaos synchronization of uncertain fractional order chaotic systems subject to modelling uncertainty is investigated. A novel synchronization strategy based on fractional sliding mode control is developed for fractional order chaotic systems. Sliding mode control is generalized to fractional order systems, and fractional order sliding mode reaching law and fractional order sliding mode surface are...
