In this paper, output feedback controller is applied to solve robust fault-tolerant problem for singular bilinear system with Markovian jump. The aim of this problem is to design a output feedback controller that ensures stochastic stability of the closed-loop system and the -induced gain from the noise signal to the estimation signal remains bounded by a prescribed value, whether the actuators are normal or abnormal. The controller can be constructed by solving a set of linear matrix inequalities. An illustrative numerical example is given to demonstrate the applicability of the approach.

Power System Oscillations

This paper addresses the design problem of robust H2 output feedback controller design for damping power system oscillations. Sufficient conditions for the existence of output feedback controllers with norm-bounded parameter uncertainties are given in terms of linear matrix inequalities (LMIs). Furthermore, a convex optimization problem with LMI constraints is formulated to design the output feedback controller which minimizes an upper bound on the worst-case H2 norm for a range of admissible plant perturbations. The technique is illustrated with applications to the design of stabilizer for a single-machine infinite-bus (SMIB) power system. The LMI based control ensures adequate damping for widely varying system operating.
