A new method based on wavelets is proposed for stability analysis of vibration control system with multiple delays. In this method, solutions of the initial-value problem of time delayed vibration control systems are approximated by wavelets. Applying wavelet collocation method, the initial-value problem of the time delayed vibration control systems is transformed to a mapping system. The stability of the original system depends on the maximal modulus of eigenvalues of the mapping matrix, and the numerical solution of the initial-value problem are obtained by solving the mapping system. Numerical examples show that the method can locate stable and unstable regions in parameter planes and produces accurate numerical solutions of initial-value problems of time delayed systems.
