Real-time network induced delay compensation with digital redesign technique

Our technological demands today require extremely challenging control solutions such as real-time applications of Networked Control System (NCS). However, due to communication protocol and shared data bus, NCS always experiences uncertain and unpredictable time delays in both input and output channels. These delays cause asynchronization between controller and plant thereby degrading the performance of closed-loop control systems. To address the concern of stability improvement in real-time, this paper proposes to utilize digital redesign technique to compensate for these network induced delays.
