Frequency Transmission Control of Local Networked Control Systems Approach
The use of Network Control Systems has been successful in the industry and therefore has opened several lines of research. Control systems over a communication network include two important considerations, control and scheduling. Co-design strategies are focused on maintaining adequate control performance and maximize the level of service. Network scheduling is the main objective to resolve because through a balanced data load is possible to maintain control performance in a desired level. This article reviews a scheduling strategy based on frequency transition modeled as a linear subsystem, this control reconfigure on line the sensors' periods. The case of study is the control of a prototype helicopter and by numerical simulations it shows the effect of changing the transmission frequency.
