A filtered predictive PI controller for wirelessHART networked control system

In recent years, increasing attention has been paid towards applying wireless technology for control. This is due to its advantages of exibility, scalability, use of fewer cables and overall reduced operational cost compared to its wired counterpart. However, the technology is often affected by stoc...
