ESQUIVEL-FLORES, O.  and  BENITEZ-PEREZ, H.. Frequency Transmission Control of Local Networked Control Systems Approach. J. appl. res. technol [online]. 2012, vol.10, n.4, pp.505-519. ISSN 2448-6736.

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.

Keywords : distributed systems; transmission frequency; control.
