In this paper, the distributed output feedback leader-following control is investigated for high-order nonlinear multiagent systems (MASs) using the dynamic gain method. The linear-like distributed output feedback controller is designed without using the recursive method to overcome the “explosion of complexity” problem and further relax the conditions on the nonlinear functions of the MASs. First, the distributed reduced order dynamic gain observer is constructed for the ${i}$ th agent to estimate its unmeasured state variables, in which the output information of its neighbors are used. Second, the linear-like output feedback controller is designed such that the outputs of the followers track the leader’s output, and the tracking error could be arbitrarily small. Finally, the simulation examples are given to illustrate the effectiveness of the proposed method.

动态增益方法的高阶非线性多主体系统分布式输出反馈前导跟随控制

本文研究了采用动态增益方法的高阶非线性多主体系统（MAS）的分布式输出反馈先导跟随控制。设计线性分布的输出反馈控制器时，不使用递归方法来克服“复杂性爆炸”问题，并进一步放松了MAS非线性函数的条件。首先，为第（i）$个代理构建分布式降阶动态增益观察器，以估计其未测量的状态变量，其中使用其邻居的输出信息。其次，设计线性输出反馈控制器，以使跟随者的输出跟踪领导者的输出，并且跟踪误差可以任意小。最后，
