模糊PID自整定控制在空调系统中的应用研究

在空调系统的过程控制中，由于控制对象的时滞、时变、非线性的特征比较明显，导致被控对象不容易控制。在这种系统中采用常规PID控制往往效果欠佳，而参数自整定控制却能较好地适应这些特征，因此引起了空调领域的普遍关注。以实际工程为背景，介绍了模糊PID自整定控制的相关内容及其在空调控制系统中的应用，通过实验验证了此控制方案的优越性和可行性。

Application of fuzzy self-tuning PID control to air conditioning systems

In the control process of air conditioning systems, it is not easy to keep the objects to be desirably controlled because of their obvious features such as time lag, time-variation and nonlinearity. Adopting conventional PID control for this kind of system is difficult to get a good effect. Self-tuning PID control can adapts those features better, which is widely noticed in air conditioning field. Combining a practical project, describes some knowledge about fuzzy self-tuning PID control and its application to air conditioning control systems. Verifies the superiority and feasibility of the control scheme by way of experiments.
