| Research Abstract |
In this research, we have considered practical stability and stabilizability for switched and hybrid systems composed of several subsystems that do not have common equilibrium points. Practical stability is an extension to "finite time stability" and "ultimate boundedness", which aims at convergence to a specified small region around certain desired equilibrium point. The main contribution is to analyze practical stability and to establish practical stabilizability algorithms for switched nonlinear systems including switched integrators, switched affine systems. Furthermore, with the behavior of general Lyapunov asymptotical stability in mind, we have extended the discussion to asymptotical practical stability for switched and hybrid systems, and have proposed effective algorithms for the purpose of asymptotical practical stabilizability.
