Conclusion

This study focus on the state estimation for switched linear systems with unknown inputs. An improved MDLF is constructed to analyze the continuous-time switched systems, which is helpful to further reduce conservatism compared with the traditional multiple Lyapunov-like function. The stability criterion is constructed for the switched error system with AEDADT switching. Based on the coordinate transformation technique, observers for unknown input switched systems are designed to guarantee the asymptotic state reconstruction.
