Design of large-scale time-delayed systems with dead-zone input via variable structure control. (English) Zbl 1080.93003
The authors propose a decentralized variable structure control law to stabilize an uncertain large scale system with time-delays in interconnections and dead-zones in inputs. The uncertainties and interconnections satisfy matching conditions and the proposed control law for interconnected systems is implemented independently of the delay term, and dynamics of the system with dead zone input is dominated by the sliding mode.
The line of reasoning is based on the Lyapunov function approach and the proposed design guarantees the global reaching condition of the sliding mode and the invariance condition holds. Two numerical examples are given to verify the effectiveness of the proposed design procedure.
