The Impact of Time-delay on Networked Control System and Stability Region Analysis of PID Controllers
In this paper, the impact of network induced timedelay on Networked Control System (NCS) and the weights of Sensor-Controller time-delay and Controller-Actuator time-delay is analyzed by simulations. Furthermore, the effects of plant parameters on stability region of PID controllers in first-order and second-order systems with time-delay is also studied. Finally, an open-loop zero was inserted into the plant-unstable second-order system with time-delay so that the stability region of PID controller gets effectively enlarged.
