Abstract

The gases separation from the feedwater in the deaerator is done by heating process. When the temperature inside the deaerator increases, the volume of the feedwater will decrease. Therefore, a level control system in the deaerator is needed in order to maintain the stability of the boiler feedwater supply. However, to get a good control performance, the controller tuning is required. In this study, the PI controller with feedback feedforward structure is used. Tuning parameters are obtained by using the direct synthesis method where the value of the proportional gain is 0.69 and the integral time is 28.95. Other than that, the feedforward tuning parameters are obtained by the feedforward equation where the value of the feedforward gain is 0.0001, the lead time constant is 28.95, and the lag time constant is 48.48. The controller performance is determined by analyzing the dynamic response graph from the close loop test. Based on the ± 10% setpoint changes test results, the IAE values are 0.000848% and 0.00059%, the maximum overshoot values are 1.52% and 1.86%, and the settling time values are 7130 seconds and 7150 seconds. Furthermore, on the ± 10% disturbance changes test results, the IAE values are 0.442% and 0.443%, the maximum overshoot values are 10.83% and 10.82%, and the settling time values are 6050 seconds and 6060 seconds.The abstract should summarize the contents of the paper and should contain at least 70 and at most 200 words. It should be set in 9-point font size, justified and should have a hanging indent of 2-centimenter. There should be a space before of 12-point and after of 30-point.
