This paper investigates consensus of continuous-time multi-agent system through adjusting the proportion of the current state and time-delay state in the control algorithm,supposing that its topology is fixed and a directed interconnection graph which contains a spanning tree.A sufficient condition for the convergence to a consensus is proposed and proved based on the generalized Nyquist stability criterion and the Gerschgorin disk theorem.A method is found to enlarge upper bound on the maximum time-delay,numerical simulations are shown to demonstrate the validity of the achieved theoretical results.

This paper deals with the cooperative control problem for second-order agents formation circling along meridian and parallel on a given sphere centered at a target of interest,where the direction of the target's movement is known to each agent but the target's speed is *** using local measurements of relative position,a novel distributed solution is proposed by separatively designing each agent's control input projected onto the spherical normal vector,the direction of spherical meridian and parallel.A second-order coordinated adaptive upgrade law is given to estimate the given target's speed by using adaptive backstepping and ***,a potential function is introduced to avoid the undefined angle coming from the trajectory between the poles of *** theoretical result is proved by the numerical simulation.

Multi-variable systems widely exist in the practical engineeringcontrolsystems whose performances are always severely interrupted by strong disturbances including unmodeled dynamics, parameter variations, couplings and external disturbances. Disturbance observer(DOB) is known as an effective technique to estimate disturbances and has been extensively applied for feed-forward compensation design in the presence of disturbances. Yet many disturbance observer techniques in previous literature are just used for single-input-single-output(SISO) systems or the DOBs can be applied in the multi-variable systems, but the DOBs are still SISO DOBs. A decoupled robust multi-input-multi-output neural network disturbance observer(MNNDOB) is designed for the multi-input-multi-output(MIMO) systems. Simulation results on the mixing tank show that the proposed method has better disturbance estimation performance when there are severe model mismatches compared with the MIMO linear disturbance observer.
