Sliding mode control for non linear water treatment system

The ultraviolet irradiation presents a particular solution for the water disinfection, This paper presents a new state space model of a Ultraviolet (UV) lamp, used in a water disinfection pilot unit fed by a photovoltaic source. The non linear model relates the current and the conductivity of the low pressure discharge lamp used for water treatment was developed. The sliding mode control approach of a class of non linear systems subjected to control approach for the power UV lamp and power motor-driven pump is established. Reliable results are given to show the interest of the sliding mode control of complex physical systems.
