摘要
本文针对大时滞、非线性、时变的控制对象,设计了一种Fuzzy-Smith控制器,把Smith补偿控制原理和模糊控制方法结合起来,利用Smith预估器对模糊控制进行有效的补偿,使二者的结合对于大时滞系统的控制可以达到优势互补。仿真研究结果表明,该方案具有很强的鲁棒性,能够提高系统的控制品质。本文所设计的Fuzzy-Smith控制器能够应用于温控仪表等工业过程控制对象中。
Fuzzy-Smith controller is designed especially for controlling objects with big time-lag, non-linearity and time varying. The controller combines the compensation control theory with fuzzy control method, using Smith predictor to make effective compensation to fuzzy control, thus the combination of the two has complementary advantages in controlling the big time-lag system. Simulation experiment on the controller proves that this proposal can improve the system's control quality with strong robustness. The Fuzzy-Smith controller can be applied to temperature control instrument and other controlling objects in industrial process.
