探讨了一种实用的通用型ＰＩ自校正调节器，其主要特点是利用被控对象输出波形的“特征向量”整定ＰＩ参数．整定过程中将整定规律分段线性化，使得校正过程简单、调整速度快，并且由于专家知识的运用，对被控对象模型不要求精确辨识，实用面广．
A practical universal PI self-tuning regulator is discussed. Its main feature is to use the “eigenvectors” of the controlled object to set the PI parameters. In the process of setting, the setting law is piecewise linearized, which makes the process of calibration simple and quick to adjust. And due to the use of expert knowledge, it is not required to accurately identify the controlled object model, so it has wide practical range.
