Compensation of networked control systems with time-delay

In recent years, networked control system (NCS) has been receiving much attention due to shared networkc channels with improved communication device. In NCS, data-dropout and delay are unavoidable. In practical systems, some constraints have to be considered independent of communication. A desired performance in NCS may not be achieved if the closed-loop is not designed without taking consideration of the data-dropout and delay. Therefore, the delay and/or the data-dropout in the network have to be considered in designing NCS. This paper proposes a model predictive control (MPC) based approach for NCS. The delay is described as stochastic models in order to taking them into account for generating input to actuator. The effectiveness of the proposed approach is verified by applying to an inverted pendulum.
