Abstract :
Delay compensation is becoming increasingly important due to time-varying delay characteristics over wireless network employed in WSAN-based cyber-physical control systems. Time-varying delay is hard to measure and compensate for it accurately in real-time. This paper presents a delay compensation technique with smith predictor by exploiting virtually constant delay property achieved by playback buffer. Simulation results show that the proposed scheme improves the control performance.
