Impulsive Consensus for Leader-Following Multiagent Systems with Fixed and Switching Topology
"... This paper studied the consensus problem of the leader-following multiagent system. It is assumed that the state information of the leader is only available to a subset of followers, while the communication among agents occurs at sampling instant. To achieve leaderfollowing consensus, a class of di ..."

the leader-following consensus of the multiagent system. It is found that leader-following consensus is critically dependent on the sampling period, control gains, and interaction graph. Finally, two numerical examples are given to illustrate the effectiveness of the proposed approach and the correctness
RESEARCH ARTICLE Nonlinear Consensus via Continuous, Sampled, and Aperiodic Updates
, 2012
"... We consider a first-order multi-agent system with nonlinear control protocols performing consensus. We first address the convergence properties of the continuous system. Then periodically sampled control inputs are treated, where we derive explicit upper bounds on the sampling interval to preserve g ..."

Stochastic Consensus of Single-Integrator Multiagent Systems with Inherent Nonlinear Dynamics and Measurement Noises in Directed Fixed Topologies
"... Consensus of continuous-time single-integrator multiagent systems with inherent nonlinear dynamics and measurement noises is addressed in this paper. The consensus controller is developed for directed interaction topologies. Each agent's control input is constructed based on its own state and ..."

Low-Gain Integral Control of Well-Posed Linear Infinite-Dimensional Systems with Input and Output Nonlinearities
- J. Mathematical Analysis and Applications
"... Time-varying low-gain integral control strategies are presented for asymptotic tracking of constant reference signals in the context of exponentially stable, well-posed, linear, infinite-dimensional, single-input, single-output, systems -- subject to globally Lipschitz, nondecreasing input and outpu ..."

It is shown that applying error feedback using an integral controller ensures that the tracking error is small in a certain sense, provided that (a) the steady-state gain of the linear part of the system is positive, (b) the reference value r is feasible in an entirely natural
Consensus for Multiagent Systems with Nonlinear Dynamics and Time Delays Using a Two-Hop Relay Adaptive Method
"... This paper investigates the consensus problem for multiagent systems with nonlinear dynamics and time delays. A distributed adaptive consensus protocol is proposed in which the time delays are explicitly included in the adaptive algorithm. It is shown that the resultant closed loop system involves ..."

The Application of Nonlinear Pre-Filters to Prevent Aeroservoelastic Interactions due to Actuator Rate Limiting
"... In this paper a nonlinear aeroelastic system coupled to a rate limited actuator. The aeroservoelastic system is subjected to a short time sharp edged gust. The piecewise impulse controller was found to provide both state regulation and phase compensation to the rate limited actuator. The closed loop ..."

loop system is largely insensitive to the changes in the phase lead transfer function gain, due to the switching action the controller; but sensitive to the changes in the phase lead transfer function damping ratio. The piecewise impulse controller was found to remove steady state error. 1.
Effects of Delay on the Functionality of Large-scale Networks
"... Networked systems are common across engineering and the physical sciences. Examples include the Internet, coordinated motion of multi-agent systems, synchronization phenomena in nature etc. Their robust functionality is important to ensure smooth operation in the presence of uncertainty and unmodell ..."

cases the loop gains have to be compensated for by the delay size, in order to render functionality delay-independent for arbitrary network sizes. Consensus reaching in multi-agent systems and stability of network congestion control for the Internet are used as examples. The differences and similarities
