AI总结:

针对SISO LTI被控对象,提出一种联合设计数字控制器与网络参数(调度和路由)的方法,以在控制努力、输出超调和信道带宽约束下保证稳定性并最大化阶跃响应瞬态性能指标,通过将NP-hard的多项式优化问题转化为凸优化问题实现计算可行性。

摘要:

多跳控制网络由被控对象组成,其中传感器、执行器和计算单元之间的通信由(无线)多跳通信网络支持,数据流通过传感和执行数据的调度和路由进行。给定一个SISO LTI被控对象,我们将解决数字控制器与网络参数(调度和路由)的协同设计问题,以在控制努力、输出超调和通信信道带宽的约束下,保证稳定性并最大化阶跃输入瞬态响应的性能指标。我们表明上述优化问题是一个多项式优化问题,通常是NP难的。我们提供了网络拓扑、调度和路由的充分条件,使得该问题在计算上可行,即简化为一个凸优化问题。

英文摘要:

A Multi-hop Control Network consists of a plant where the communication between sensors, actuators and computational units is supported by a (wireless) multi-hop communication network, and data flow is performed using scheduling and routing of sensing and actuation data. Given a SISO LTI plant, we will address the problem of co-designing a digital controller and the network parameters (scheduling and routing) in order to guarantee stability and maximize a performance metric on the transient response to a step input, with constraints on the control effort, on the output overshoot and on the bandwidth of the communication channel. We show that the above optimization problem is a polynomial optimization problem, which is generally NP-hard. We provide sufficient conditions on the network topology, scheduling and routing such that it is computationally feasible, namely such that it reduces to a convex optimization problem.
