Networked control systems are becoming increasingly important due to its simplicity, scalability, flexibility. However, two challenges are network delay and packet dropout. Applying a real-time queuing protocol, we are able to limit the network delay within a control period. In this way, control signals are always sent to the actuator within a fixed time interval, making the performance of the overall NCS network deterministic and predictable, as needed in real-time control applications. This paper proposes to compensate for network delay at the actuator using past control signals. They are suitable for a large number of networked control systems.
