Item Open Access Networked control systems and wireless sensor networks: theories and applications.(Taylor & Francis, 2008-11-01T00:00:00Z) Yang, Shuang-Hua; Cao, YiAbstract This special issue aims to provide innovative research work that has recently been carried out in networked control and wireless sensor networks, including both theoretical developments, experimental and/or application research. Wired and wireless networks have been used as a platform in the remote monitoring and control. The applications cover a wide range from natural monitoring to ambient awareness, from military to surveillance, and from industrial plants to domestic home environments. This preface first introduces the basic concepts of networked control and wireless sensor networks, then presents the challenges in these areas, and finally summarises the five papers included in the special issue.Item Open Access Predictive control for the ALSTOM gasifier problem.(Institution of Electrical Engineers, 2006-05-09T00:00:00Z) Seyab, R. K. A.; Cao, Yi; Yang, Shuang-HuaModel predictive control (MPC) has become the first choice of control strategy in many cases especially in the process industry because it is intuitive and can explicitly handle MIMO (multiple input multiple output) systems with input and output constraints. The authors implemented a simple MPC algorithm based on the state space formulation to control the ALSTOM gasifier. Among three operating conditions of the plant, 0% load condition is identified as the worst case. A linearised state space model at 0% load condition of the non-linear plant is adopted as the internal model for performance prediction. Because of this choice, the control system comfortably achieves performance requirements at the most difficult load condition. Meanwhile, the case study shows that the model is also adequate to pass all tests under other load conditions specified in the benchmark problem. The MPC algorithm uses standard formulation and off-the-shelf software with a few tunable parameters. Thus, it is easy to implement and to tune to achieve satisfactory performance.
