A rising number of feedback control systems replace their hardwired connections with intermediate networks. These types of control systems are called Networked Control Systems (NCSs) and are often very sensitive to delays in the network, i.e. on their feedback loop. Especially non-uniform delays pose a problem for most controller implementations. In light of this, research yielded different approaches to stabilize such systems and make them robust. Some of these solutions approach the problem at the controller itself, while others try to mitigate delays and disturbances within the intermediate network. These approaches have one thing in common: Their results are difficult to verify and hardly comparable. This thesis presents and explains the setup of a demonstrator which can be used to test and compare solutions acting in different intermediate networks using the same, predictable control system. To achieve this, the required theoretical background of control systems is revised and the setup of a inverted pendulum as a NCS demonstrator is explained in detail. Furthermore, different networking setups and their properties are described and documented.
