The Design of State Observer for Interval Switched System
Abstract:The article studies the design of the state observer for a class of interval switched systems. On the basis of the approach of common Lyapunov function and multiple Lyapunov function, we design the state observer and the relative switching strategy. Sufficient conditions of asymptotic stability for error systems are given in the form of linear matrix inequality. Simulations show the correctness and effectiveness of the state observer.
