| Outline of Final Research Achievements |
We have considered practical stability and stabilization of switched systems composed of several subsystems that do not have common equilibrium points and have quantization errors. We have proposed how to adjust quantization parameters together with switching laws such that the state of switched systems converge to certain desired point in the sense of practical asymptotic stability. Furthermore, considering quantizers' feature, we have studied quadratic stabilization and L2 gain property of switched affine systems. We have shown that if a convex combination of subsystem matrices is Hurwitz and another convex combination of affine vectors is zero, then we can design a state-dependent switching law and an output-dependent switching law such that the entire switched system is quadratically stable. The result has been extended to L2 gain analysis under state feedback, and to the case where the convex combination of affine vectors is nonzero.
