Talk Title: Stable decentralized control of complex dynamical systems
Abstract:
In this talk, we present a simple approach to stabilizing control of a complex dynamical system which consists of several mutually coupled subsystems. We develop the control in two steps- First, we define a nominal system, in which the subsystems are uncoupled. This is done by defining nominal subsystems which are obtained by approximating each subsystem based on locally available states only. Stabilizing (nominal) controls are then synthesized for each nominal subsystem which are also optimal. In the second step, we force the actual system (with coupled actual subsystems) to track the trajectories of the controlled nominal system as closely as desired by user, thus ensuring stability. This is achieved by use of a generalized sliding surface controller in conjunction with the nominal controller.
