Sampled-data output consensus problem has been firstly considered within co-design framework where control gains and sampling periods are incorporated together. In construction of co-designed controllers, we firstly introduce a scaled coordinate transformation for the original system in the continuous-time domain. Then design of sampled-data controllers with absolute/relative damping and stability analysis of closed-loop system have been conducted directly in discrete-time domain. Main novelty of the co-design method lies in that the sampling period can be arbitrarily large due to the compensation of control gains. Compared with previous work on sampled-data consensus protocols, conservatism on allowable sampling periods has been greatly relaxed and more flexibility has been provided for digital implementation of the obtained sampled-data controllers. Simulation studies with different sampling periods are also provided to illustrate the effectiveness of the co-designed sampled-data output controllers.

多智能体系统共同设计的采样数据输出共识

在将控制增益和采样周期结合在一起的协同设计框架中，首先考虑了采样数据输出一致性问题。在协同设计控制器的构建中，我们首先在连续时间域中引入原始系统的缩放坐标变换。然后直接在离散时域中进行了具有绝对/相对阻尼和闭环系统稳定性分析的采样数据控制器的设计。协同设计方法的主要新颖之处在于，由于控制增益的补偿，采样周期可以任意大。与之前关于采样数据共识协议的工作相比，允许采样周期的保守性已经大大放宽，并且为获得的采样数据控制器的数字实现提供了更大的灵活性。还提供了具有不同采样周期的仿真研究，以说明共同设计的采样数据输出控制器的有效性。
