  4. 2. Stability Properties of Switched Dynamical Systems A Linear Matrix Inequality Approach

    Author : Marcus Rubensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The dynamical properties of many natural phenomena are traditionally described by smooth differential equation models. The use of automated control structures imposes new behaviors on the controlled system. Actions are often organized in a logical manner. Switched dynamical models are a natural extension to smooth differential equation models. READ MORE
