The controller is designed to switch among subsystems to stabilize the hybrid system by a variable structure switching law. The concept of the sliding sector is used in the paper to show that there exists an area, inside which a Lyapunov function decreases, for any system no matter whether it is stable or unstable. A Lyapunov function is designed by assuming that a stable convex combination of the subsystems exists. Then the VS controller is designed such that the Lyapunov function decreases in every period for the hybrid system to be switched once through all subsystems. The extremum seeking control algorithm is used to determined the switching rule such that the Lyapunov function track a pre-determined decrease signal. The proposed VS system is quadratically stable. Simulation results are given to show the convergence of the proposed VS control system","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.

The solution is designed as an iterative algorithm of refinement of the approximate solution obtained via application of the describing function (DF) method. The algorithm is based upon the transformation of the original nonlinear system into an equivalent nonlinear system and the concept of the periodic signal mapping applied to the latter. The solution is sought for as a fixed point of the periodic signal mapping. It is shown that the DF method can be viewed as a method of approximate calculation of the periodic signal mapping. It is proved via the exact approach that for the considered type of nonlinear systems, the necessary conditions of sliding mode existence, previously obtained via the DF method, are valid.

The algorithm employs a time-varying switching plane. At the initial time the plane passes through the point determined by the system initial conditions in the error state space. Afterwards, the plane moves with a constant velocity to the origin of the space. In order to select the switching plane parameters, the integral of the time multiplied by the absolute error (ITAE) is minimized. Two types of the input signal constraints, i.e. a conventional constraint expressed by an inequality and an elastic constraint which allows the threshold value of the input signal to be slightly exceeded are considered. In both cases the switching plane is chosen in such a way that the reaching phase is eliminated, insensitivity of the system to the external disturbance and the model uncertainty is guaranteed from the very beginning of the proposed control action and fast, monotonic error convergence to zero is achieved","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.
