| Abstract: | An intelligent valve control scheme and a fuzzy control strategy incorporating the cascade PID with an expert auto tuning scheme are suggested for the first and second step spraying,respectively of a 300MW low multiply combined circulation boiler with the working condition changing frequently and the strong steam temperature dynamic time varying nonlinear property.The system design is implemented by using a distribute control system.The industrial application results show that the main steam temperature control method suggested in this paper has better control performance and stronger adaptive capability to the noises than those of the normal control method. |
