摘要
针对调和汽油辛烷值的控制问题,提出了一种基于非线性预估器的控制系统。该方案基于Smith预估器的结构,结合调和工艺机理设计了专门的非线性预估器,并详细讨论了非线性预估器的参数选择。仿真结果表明:基于非线性预估器的调和汽油辛烷值控制系统性能明显优于经典PID控制策略。
Aimed at the control of octane number (RON) of the blended gasoline, a control system based on a nonlinear predictor was proposed, which has the nonlinear Smith predictor based and the gasoline blending process mechanism considered to design a special nonlinear predictor and its parameters selection were discussed. The simulation result shows that this predictor’s performance outperforms that of the classical PID control strategy.
