Study on Simulation of Multi-Loop Networked Control System

Multi-loop NCS is widely used in machinery networked manufacturing production line. The performances of NCS are influenced by the network scheduling and some uncertainty factors, such as transmission rate, delay, loss rate of packet, disturbance, and so on. Considering these influence factors, a simulation model of a multi-loop is constructed using TrueTime toolbox of Matlab software. The related study methods of performance of NCS are given. As the result of simulation, the performances of multi-loop NCS are observed and analyzed. The work done in this paper is very meaningful and helpful to further make related control strategy improving the research on performances of multi-loop NCS.
