It avoids the complexity of large-scale system design by focusing on individual control systems. In the dual-rate configuration, the plant under control is first stabilised by a local controller with a high sampling rate. The remote proportional integral derivative (PID) controller, which regulates the output according to the desirable reference, adopts a low sampling rate to reduce load on the network. The upper bound of the remote PID controller's sampling time which meets the requirement on control performance is derived and a simple tuning method for the remote PID controller is presented. Simulation and real-time examples are provided for illustration. © 2010 The Institution of Engineering and Technology. | Source Title: | IET Control Theory and Applications | URI: | http://scholarbank.nus.edu.sg/handle/10635/82752 | ISSN: | 17518644 | DOI: | 10.1049/iet-cta.2008.0572 |
