Abstract


For most of our small and medium sized power plant boiler feed water systems are still using conventional instrument to control, difficult to achieve better control effect of the shortcomings of industrial boiler feed water system of the computer monitoring technology to enable it to adapt to the current Intelligent Control needs. This thesis is based on feed water system has a more complex dynamic characteristics of proposed performance indicators weighted generalized predictive control algorithm is applied to the control of the system to reduce the \The method is very important predictive control technology of a branch. Through the industrial boiler drum water level dynamics of the system analysis and online identification , determine the system model , the parameters to adjust the system , the water supply as a control volume, water level as output, steam disturbance feedforward can be measured as the amount of interference , as well as the control and output volumes were weighted to carry out a systematic simulation. This algorithm will be used in industrial boiler feed water control system simulation studies show that the control scheme exhibits good control quality, and can adapt to changes in the controlled object parameter has strong robustness and adaptability , it with the standard generalized predictive control algorithm, the traditional PID algorithm, it is much better than the two control algorithms.
