Research on coordinated control based on fuzzy neural network applied to pressure control of once-through steam generator

摘要

Because the water cubage is small, heat energy is few in the once through steam generator (OTSG), disturbs possess uncertain and non-linear, and the pressure of outlet steam is controller difficultly during load changes, on-line adjusted coordinated control based on fuzzy neural network of standard model is applied to control the outlet steam pressure of OTSG. The simulation results shows that the controller has on the better performance that overshoot and settling time turn smaller than that of PID controller.
