Abstract: The traditional stable control systems need strong conditions of quadratic Lyapunov, exponential or asymptotic stabilization. Using techniques of switched control or convex combination, the unstable subsystems can be convergent in need of weak conditions, such as convergent subspace. This paper analyzed the convergence of perturbed switched systems. Three switching laws and algorithms of state feedback, threshold restriction and state delay were designed. The state estimation and error analysis were achieved in observed switched systems with state estimator. Through simulation by Matlab procedures, some optimal parameters were found and the switched experiment data were analyzed and compared, which showed the stabilization and convergence performance under different switched laws.
