| 摘 要： | 针对漂白温度控制系统具有纯滞后、模型参数不稳定的特点，在传统的史密斯控制的基础上，结合模糊控制方法，设计了Fuzzy-Smith控制器。该方法利用了Smith预估控制来克服系统纯滞后的特点，也利用了模糊控制对模型参数要求不精确的特性。仿真结果表明：该控制算法具有很强的鲁棒性，有效地抑制了大滞后的影响，对参数变化具有很强的适应性，能够较好地实现对漂白温度的控制。

| Abstract: | Aimed at large time-delay and parameters instability characteristics of the bleaching temperature control system, with the conventional Smith controller and the Fuzzy control theory, the Fuzzy- Smith eontroller is designed. This method takes the advantage of Smith predictive control for conquering a large time-delay and Fuzzy control for achieving perfect control result in inaccurate parameters model. Simulation result shows that the algorithm has the following advantages： strong robustness, efficient achievement of inhibiting the large time-delay, good adaptabilities for various in the parameters. This approach obtains preeminent control performance to bleaching temperature control system. |
