Both the Lap lace Transform and the Para real family of algorithms promise to provide completely parallel in time and space computational results. Given a random time dependent partial differential equation it is unclear which algorithm will run faster. We define the algorithms in question, including more specific details than usual. We define interesting parallel environments, some of which do not...
We study the boundary exact controllability for the semilinear Schrodinger equation defined on an open, bounded, connected set Ω of a complete, n-dimensional, Riemannian manifold M with metric g. We prove the local exact controllability around the equilibria under some checkable geometrical conditions. Our results show that exact controllability is geometrical characters of a Riemannian metric, given...
The tracking control and chaotic synchronization problem for a class of continuous time uncertain chaotic system is studied. A fuzzy sliding mode variable structure control approach is proposed. A controller based on the fuzzy sliding mode variable structure approach is designed and the stability of the control system is proved by Lyapunov stability theory. Using this controller, two chaotic systems...
For Kalman filter-based data fusion in sensor networks, based on the weighted least squares (WLS) method, two distributed measurement fusion Kalman filtering algorithms are presented in terms of the average weighted measurements and the average inverse-covariance matrices, where the second algorithm is equivalent to the micro-Kalman filter (or mu-Kalman filter) derived from the centralized Kalman...
In the doubly-fed wind generator system, a bi-directional converter is needed to control the energy bi-directional flow due to the different operation of generator. Doubly-fed PWM converter with attractive characteristics, such as well sinusoidal waveform of input current, high power factor, low THD (total harmonic distortion) to the grid and motor, and bi-directional conversion, could better meet...
