Abstract: This paper presents an robust adaptive controller being used to address some of the uncertainties in the system model, including unmodeled dynamics, parameter variations, and the presence of perturbations in the automatic control system of a real sucker-rod pump. The results show that the control systemis able to satisfactorily handle uncertainties and variations, such as in the pumped fluid composition, a very common situation in real production fields. Experimental tests conducted in a real plant validate the robustness of the control algorithm.
