Abstract

The different effects of the sensor-to-controller and the controller-to-actuator delays in networked control systems, are investigated within the packet-based control framework. The study starts with identifying the specific control strategies that make those two delays different for the system. The problem is then carefully formulated and theoretical analysis is conducted, revealing that under certain conditions the sensor-to-controller delay can cause less deterioration of the system performance than the controller-to-actuator delay. This result is verified by a numerical example and has its practical guidance value.
