Comparison between PID controller and fuzzy sliding mode control (FSMC) on super heater system

Abstract

Super heater, a component in a boiler, is an important component in a steam power plant system. It serves to transform the heat into superheated steam to spin a turbine. The steam temperature must be carefully controlled, to ensure good quality of steam. For the best performance of steam power plant (PLTU) 3-4 PJB UP Gresik, Indonesia, the temperature of superheated steam must be achieve 814 K. In this paper was designed PID controller super heater system and analysis of the performance of the system by comparing PID and FSMC. PID Controller can generate steam temperature stable at 814 K. While the FSMC controller generate steam temperature stable at 814.097 K. Thus, it was concluded that PID controller can generates more accurate steam temperature than FSMC. However when the system get a disturbance, FSMC can handle it better than PID controller.
