This paper develops a new decentralized event-triggered control strategy for large-scale nonlinear systems. The control systems are assumed to be transformable into an interconnection of input-to-state stable (ISS) subsystems with the sampling errors as the inputs. For the subsystems, the events of data sampling are triggered by appropriately choosing threshold signals, which are independent with...
This paper presents a new approach to event-triggered control of nonlinear systems. The study is directly based on the notion of input-to-state stability (ISS) and its essential relationship with robust stability. Our main result is an ISS gain condition for event-triggered control of nonlinear systems. It is proved that infinitely fast sampling can be avoided with an appropriately designed event...
This paper presents a cyclic-small-gain approach to distributed output-feedback control of multi-agent nonlinear systems. Through novel distributed observer and control law designs, the closed-loop distributed system will be transformed into a large-scale system composed of ISS subsystems, the ISS gains of which can be appropriately assigned. The stability of the closed-loop distributed system is...
This paper presents a fundamentally novel approach to quantized output-feedback control of nonlinear systems. The advances made toward this challenging, yet important, problem are a seamless integration of dynamic quantization and the recently developed cyclic-small-gain theorem. The constructed output-feedback quantized controller guarantees the input-to-state stability (ISS) property for the closed-loop...
This paper presents a Lyapunov formulation of the cyclic-small-gain theorem for dynamical networks composed of interconnected discrete-time input-to-state stable (ISS) subsystems. ISS-Lyapunov functions for dynamical networks satisfying cyclic-small-gain are constructed from the ISS-Lyapunov functions of the subsystems.
In this paper, a class of hybrid switched systems with impulsive effects is considered. In light of the conventional input-to-state stability (ISS) and its various extensions (i-ISS, e-ISS and ei-ISS), we propose novel criteria on ISS, i-ISS, e-ISS and ei-ISS for these impulsive switched systems. The obtained results show that an impulsive switched system may be ISS, even when the continuous-time...
