Sliding Mode Regulator for the Perturbations Attenuation in Two Tank Plants

The perturbations are the disturbances of motion presented in the plant inputs which affect the motion of the output and states. In this paper, a sliding mode regulator is recommended for the perturbations attenuation in the plant output and states. The novelty of the advised regulator is that it does not employ an observer for the perturbations estimation; consequently, it is more compact. The asymptotic stability of the regulator is ensured via the Lyapunov approach. The mentioned regulator is employed in two tank plants prototypes.
