摘　　要：根据常规PID控制算法和模糊控制算法的特点,作者提出了一种将这两种算法结合在一起的复合控制的新型算法。这种算法的特点是利用人工经验对PID控制的参数进行在线自动整定,从而改善闭环系统性能,提高调节品质指标和适应能力。文章详细介绍了该算法的基本原理和实现方法,并给出了一些计算机实时控制的试验结果,以此说明文章提出的新型算法的可行性。The author proposes a new algorithm, combining fuzzy control with the conventional PID regulation in accordance with botch characteristics. The advantage of this new algorithm lies in the ability to realize an on-line auto-tuning of PID control parameters by making use of the operators' experiences. As a result, the performance indices of the closed loop system and the robustness of the controller are improved. In this paper, the principle of this new algorithm and the way to its implementation are described in detail. Also, some experimental results of the real-time control by computer are given, showing that the control algorithm developed in the paper is feasible.
