Stability Analysis of PID Control of Aero-engine Software Defined Control System under Nodes Faults

A distributed aero-engine PID controller implementation scheme based on nocenter and peer to peer wireless network is proposed in this paper. The basic method is to make the PID controller virtualized and then distribute them in the nodes of the wireless network, the control task of the system is the synthesis of node tasks of multiple wireless network, and there is no special controller node in the system. In order to deal with the potential faults of nodes in the wireless network, tasks have the ability to migrate among nodes. Based on the analysis of complex frequency domain theory, task migration has less impact on the system response, Finally, the influence of task migration on the system is simulated and analyzed in the MATLAB/Simulink environment, simulation results are consistent with the theoretical analysis, the availability of the designed control system is proved.
