In this study, we have a research of the design and implementation of co-simulation platform for wireless networked control systems based on Simulink and OPNET. The real time simulation platform for wireless networked control systems were designed and realized by using Simulink and OPNET. Simulink and OPNET were adopted to simulate the real time control and network performance separately. The communication between Simulink and OPNET was realized by using the technology of MATLAB engine

... . Combining the virtues of Simulink and OPNET, Co-simulation for WNCS was implemented. A simulation example of wireless networked system was given. It clearly shows that the data transmission of wireless channel was impacted on Simulink model. Simulation results became more authentic and idealistic simulation environment of OPNET was overcome. Thus the effectiveness of the Co-simulation platform based on Simulink and OPNET was proved.
