Continuous time H-infinity filter with asymptotic convergence
No full textIn this paper H-infinity, a posteriori filter (HIPF) is converted to a continuous time H-infinity (HI) filter. Then, an observer is presented which uses the gain and the state error Gramian from the continuous time HI filter (CTHF). Asymptotic stability result of the observer’s error dynamics is derived using the Lyapunov energy functional. The performance of the CTHF is evaluated using numerical simulations carried out in MATLAB. These results establish the local stability of the underlying CTHF. This type of result is novel in the literature on HI theory of filters and the observers
Water quality of the poza honda dam and other water points down
Get PDFThe phenomenon of pollution of water basins is eliminating many potential water resources. Most of the pollution in Ecuador comes from household waste and agricultural chemicals, especially along the coast. One of the activities in the management of the water resource is the periodic monitoring of the bodies of water, being able to determine the different changes that occur and to influence through preventive actions that manage to reduce the pollution. The water resource is the articulating axis of all the activities in a territory and therefore of the populations that develop different productive activities that not only depend on the quantity and quality of this resource but also generate alterations to the natural state of the same. In the investigation, the monitoring of the quality of the water in different points of the Poza Honda dam and of the river Portoviejo is carried out. The study aims to manage the pollution processes that occur in the aquifer, due to the depositions of domestic, industrial and agricultural wastewater not controlled to be discharged
