NCS flexible experimental system with network load controlled

Networked control system has many different characteristics compared with the traditional control system, so it is necessary to do some researches on strategies of networked control systems. In order to research in this area, establishing NCS simulation research platform is extremely important. A design scheme of NCS flexible researching platform is proposed, in which a switch and three computers are utilized to constitute a typical NCS, and the implementation of the scheme is completed well. Finally, with a typical second-order system model, some experiments under PID algorithm in different network load are carried out. From the experimental results, feasibility and effectiveness of the scheme of NCS research platform proposed in this paper are verified.
