In this paper it is presented an improvement of the temperature loop regulation of the steam overheated in a boiler BKZ-340-140-29M of 100 MW. The study is carried out in the Thermoelectric Máximo Gómez. The proposed consists in a two degree of freedom PID control and measure filtering. The design, that include a robust criteria, has like a fundamental objective the load disturbances rejection produced by variation in the steam flow. The measurement noise is solving using filtering process output with a second order filter. The setpoint weighting it is used to improve the setpoint changes. The proposed is compare with the performance of the current implemented controller in the loop. The results confirm the benefits of design, guaranteeing a better efficiency of the loop.

Keywords : process control; PID control; design; boilers; robustness.
