N2 - This paper proposes a Software Defined Control System (SDCS), which is a fully distributed controller scheme based on a fully connected cluster. The characteristic of SDCS is that the control task is virtualized into multiple Virtual Control Tasks (VCTs) and distributed on nodes with capabilities of computing and memory in the wireless network, there is no core node in the control system. The topologies of the wireless networks are inherently unstable, through constructing a Set of Migratable Nodes (SMN), a dynamic mapping relationship between VCTs and nodes to cope with the impact of potential network node failures on the function and performance of the control system is established. By equating the mapping relationship adjustment process to an external square wave pulse disturbance, the stability of the system under changing the mapping relationship is analyzed. In the scheme, the wireless network itself acts as a dynamic distributed controller, instead of using a particular core node to execute the control task, the distributed design of the controller and the dynamic mapping relationship above enhance the flexibility and the reliability of the control system. The digital simulation analysis is carried out in the MATLAB/Simulink environment, the results demonstrate the availability and effectiveness of the proposed scheme.
