  The aim of this work is to compute a level backstepping control strategy for
a coupled tanks system. The coupled tanks plant is a component included in the
water treatment system of power plants. The nonlinear-model of the process was
designed and implemented in Matlab- Simulink. The advantages of the control
method proposed is that it takes into consideration the nonlinearity which can
be useful for stabilization and a larger operating point with specified
performances. The backstepping control method is computed using the nonlinear
model of the system and the performance was validated on the physical plant.
