改进型模型参考自适应Smith预估控制算法在合成氨中的应用

Modified Model Reference Adaptive Smith Predictor and Its Application to Ammoniation

本文提出的改进型模型参考自适应预估控制算法是克服大时滞、有扰动及被控过程参数时变的有效新型算法。理论分析及对合成氨H_2/N_2控制的计算机仿真结果表明,该法在抗干扰能力及鲁棒性方面优于当前其它的自适应Smith预估控制算法。

An algorithm for modified model-referenced adaptive predictor control is presented in this paper. This new effective algorithm is very suitable for control system with large delay, disturbance, and time-varying parameters. The results of theoretical analysis and computer simulation for a H2/N2 system of synthetic ammonia show that the method presented here for prediction of the thansient response to disturbance and robustness are better than now algorithm for available model reference adaptive Smith predictor.
