Controllability of a Forkker-Planck equation, the Schrodinger system, and a related stochastic optimison, under proper assumptions. Theorem 2 gives a sufficiency condition concerning the given initial and terminal data for that solution to exist. Theorem 3 states that v* is an optimal feedback control for a stochastic optimal control problem with constraint on the end-state, termed ., and further

Stability robustness of linear feedback controlled flexible mechanical systems,ng controller is designed based on a rigidified model, i.e., a model in which some of the flexible components are assumed rigid, it is not true that this controller also stabilizes the ‘real’ flexible system. We present a condition which guarantees that a stabilizing controller whose design is based

Predictive controller and estimator for nasa deep space network antennas,e control law. This approach has been used for the design of tracking controllers for the NASA/JPL 70-m antennas. Several tracking scenarios have been tested (step input, constant rate rise and fall, raised cosine trajectory), and significant improvement of performance has been observed. A wider ban

Observers for controllers with matched uncertainty in A, B and C matrices,s, is assumed to satisfy certain matching conditions. Lyapunov techniques are used to establish sufficient condition for stability for a given uncertainty bound. In particular, sufficient conditions are obtained that, if met, guarantee stabilization regardless of the size of the uncertainty.
