A test bed for research and teaching in fault-tolerant control (FTC) systems is presented. The laboratory plant is based on an industrial reverse osmosis desalination plant equipped with standardized components, which introduces more realism and robustness into the experiments. This paper describes the plant, the mathematical model of the system and an illustrative experiment. Moreover, the problem...
This paper presents a new method based on the algebraic Riccati equation for designing robust reliable Hinfin control laws for plants with structured uncertainty. The design method consists of incorporating information on the plant uncertainty into the algebraic Riccati equations(ARE) used for nominal Hinfin disturbance-rejection designs. The development of the reliable Hinfin controllers assumes...
Implementing a control system over a communication network induces inevitable time delays and packet dropout that degrade performance and can even cause instability. One of the most effective ways to reduce the negative effect on the performance of networked control system is to reduce network traffic. In this paper, adjustable deadbands are explored as a solution to reduce network traffic in networked...
This paper discusses the problem of designing fault tolerant compensators that stabilize a given system both in the nominal situation, as well as in the situation where one of the sensors or one of the actuators has failed. It is shown that such compensators always exist, provided that the system is detectable from each output and that it is stabilizable. The proof of this result is constructive....
