    Abstract

    In this work, different strategies to compensate nonlinearities generated by valves in flow control loops were compared. The identification for an incompressible flow process was made through a plant test and a computer control system was developed. In this system a PI linear controller and four different compensation strategies were implemented using LabVIEW™. The comparison was made using the integral of the absolute value of the error, settling time and overshoot as performance indexes. The compared strategies allowed improving the performance of the linear controller in the actuator saturation zone. In conclusion, using these algorithms can be considered to replace elements as self-tuning controllers or nonlinear positioners that raise the inversion and maintenance costs of the plant.
