摘      要：Networked and interconnected systems denote a class of systems that consists of physically coupled subsystems that can exchange information via a communication network. This paper presents a new design method for tracking controllers, which guarantee that the output of each subsystem follows a specified trajectory. Each controller is synthesised by a design agent that is introduced as a local component with limited knowledge of the overall system. Each design agent uses the network to gain information that is necessary for the controller synthesis. The information exchange takes places exclusively at design time and concerns an important aspect of this work. The method presented in this paper extends classical two-degree-of-freedom controllers by decoupling units. These units are essential for achieving the desired tracking. It is proven that the proposed extension yields the desired trajectory tracking. A simulation study demonstrates the applicability. © 2018
