工業(yè)鍋爐控制系統(tǒng)是一個復雜的時變動態(tài)過程，傳統(tǒng)的控制算法很難使之達到理想的
控制效果和較高的自動投運率。本文采用廣義預測控制和具有比例積分結(jié)構(gòu)的廣義預測控制及灰色廣義預測控制分別對鍋爐的汽包水位、燃燒系統(tǒng)進行有效的控制，并對系統(tǒng)的性能進行定量定性分析。仿真結(jié)果驗證了它們具有魯棒性好、跟蹤快速和抑制干擾能力強等特點。應用先進控制算法對工業(yè)鍋爐進行控制，獲得了優(yōu)良調(diào)節(jié)品質(zhì)、提高了燃燒效率、實現(xiàn)了節(jié)約能源，具有顯著的經(jīng)濟效益和社會效益。

Abstract: Combustion system for industrial boiler is a complicated time-varying and dynamic
process, and it is hard to achieve ideal control performance and higher rate of automatic operation with conventional control arithmetic. In this paper, generalized predictive control method, generalized predictive control with proportion and integration structure method and grey generalized predictive control method are used to control the water level and combustion system. The performance of this new control system is analyzed in this paper and the simulation results show that this new control method has better robustness, quick tracking and good resistant disturbances. So based on these advanced control methods, the industrial boiler control system introduced in this paper can get good regulation quality, enhance combustion efficiency and realize energy-saving, which has remarkable economic benefit and social benefit.
