Abstract
This paper deals with the flatness-based approach for sensorless control of the three-tank system. Two main characteristics of the proposed control deserve to be mentioned. Firstly, the relative simplicity of implementation compared with the other advanced output feedback controller. Secondly, the estimation of the non-measurable states using a continuous-discrete time observer which can provide, even for weakly sampled output, all the missing states. Simulation and experimental results show the applicability and the efficiency of the proposed control scheme
