Posidonia oceanica is of particular interest in environmental studies for its ecological and economical importance in Mediterranean coastal environments. The plant is a source of direct and indirect food for marine organisms and it contributes greatly to increase the content of oxygen in the water. Grasslands of Posidonia oceanica represent a biological indicator of pollution and of the physio-chemical...
In this paper we consider the problem of driving to zero by means of state feedback the state of a nonlinear plant when only an approximate model of the plant is known and the information about its state is sampled. To this aim, we develop a specific model based control scheme and, under suitable hypotheses, we give a sufficient condition, in terms of length of the sampling interval and of other design...
