Application of NPC in wireless networked control systems

With the development of wireless communication technology, wireless network has been introduced into networked control system named WNCS. The wireless network brings some challenging issues. Here we consider three sources: ambient wireless traffic, block fading, and multipath fading. Based on the mathematical models of them, a wireless network is emulated. Networked predictive control (NPC) is then presented and used to make an inverted pendulum stable in the simulation. In the Simulink diagram the wireless network modules, the predictive controller, and the compensator are all implemented by C-MEX s-function. And the simulation result shows the effectiveness of the control scheme.
