This paper considers the distributed quadratic stabilization problems of uncertain continuous-time linear multiagent systems with undirected communication topologies. It is assumed that the agents have identical nominal dynamics while subject to different norm-bounded parameter uncertainties, leading to weakly heterogeneous multi-agent systems. A distributed controller is proposed, based on the relative states of neighboring agents and a subset of absolute states of the agents. It is shown that the distributed quadratic stabilization problem under such a controller is equivalent to the H∞ control problems of a set of decoupled linear systems having the same dimensions as a single agent. A two-step algorithm is presented to construct the distributed robust controller, which does not involve any conservatism and meanwhile decouples the feedback gain design from the communication topology. Furthermore, the distributed quadratic ∞ control problem of uncertain linear multi-agent systems with external disturbances is discussed, which can be reduced to the scaled H∞ control problems of a set of independent systems whose dimensions are equal to that of a single agent.

This paper considers the simultaneous attack problem of multiple missiles against a maneuvering target. Different from most of the existing literature in which the simultaneous attack problem is formulated as a consensus problem of missiles＇ time-to-go estimates, this paper formulates it as the consensus problem of missiles＇ ranges-to-go. Based on this strategy, novel distributed guidance laws are proposed to solve the simultaneous attack problem with the target of unknown *** control method is introduced to estimate the upper bound of the target＇s acceleration. The effectiveness of the proposed guidance laws is verified both theoretically and numerically.

In this paper, a robust adaptive tracking control law is designed and optimized for a multistage hypersonic vehicle（HV） tracking reference command in the existence of unknown but bounded varying system uncertainties during ascent *** original problem is transformed into a second-order error tracking system. Based on nonlinear dynamic inversion control and robust adaptive control, the proposed approach can resist model uncertainties and achieve tracking to the reference of angle of pitch, and the stability of the closed-loop system is theoretically proved. Simulation results demonstrate the effectiveness of the control law under the condition of certain specific uncertainties. Moreover, a cost function that represents the consumption of controller and integrated tracking error is introduced. Then, parameters of the control law are optimized with genetic algorithm（GA）, and the ultimate optimized parameter combinations for nominal and uncertain systems are directly tested.
