【摘要】 本文针对沸腾炉这个复杂的多变量时延对象,提出了一种具有多变量解耦Smith 预估补偿控制的燃烧系统控制方案,数字仿真表明,此方案较一般单环控制性能优良,具有较好的动态性能与稳态精度,仿真实验证明了本方案的可行性与有效性。更多还原

【Abstract】 The FBB combusion system is a complex multivariable system with large time delay,BY means of on the spot experiment,the.model of the FBB combustion system have been gained in this paper,According to this model a FBB combustion control scheme with multivariable decoupling and Smith predictor control have been presented.Theoretical analyses and digital simulation results show that this control scheme has better perfor mance and higher accuracy than those of a single-loop PID control system and it is reliable and effective.更多还原
