| 摘 要： | 首先，针对互联参数不确定的线性动态网路系统，利用部分变元稳定性理论对系统进行线性变换，将一致性问题转化成部分稳定性问题，从而得到以线性矩阵不等式（linear matrix inequality，LMI）形式给出的一致性判据，并得到基于参数依赖的Lyapunov 函数的静态输出反馈控制器设计方法。进一步对于节点系统为具有Lure 性质的非线性网络系统，考虑状态互联不确定性、控制器互联不确定性及非线性不确定性，运用Kalman-Yakubovich-Popov（KPY）引理、Schur 补等相关引理得到使得网络系统一致的新的判据，并设计静态输出反馈。最后，通过两个数值案例验证本文方法的有效性。 |

| Abstract： | According to the linear dynamic network system with uncertain parameters, we use the stability theory of partial variables, and the linear transformation matrix to convert the consensus problem to the partial stability problem. By using Lyapunov method and the projection theorem, we give the consistency criterion in the linear matrix inequality (LMI) form, and the static output feedback controller parameters are obtained by using the criterion. Furthermore, we deal with the system that the node is a nonlinear system with Lure type. Meanwhile, the system with interconnection uncertainty and controller parameter uncertainty is taken into account. Based on the circle criterion, frequency domain criterion is obtained, then we use Kalman-Yakubovich-Popov (KYP) lemma and Schur lemma to get the time domain criterion in the LMI form and the method of the static output feedback controller is proposed. Finally, numerical examples are presented to illustrate the efficiency and applicability of the proposed methods. |
