一、问题的提出 目前国内外线性自动调节理论中的两种方法:负反馈调节与前馈调节。在使用中有时将这两者机械的结合起来,但都没有改变自己原有的特征:负反馈调节系统不能直抵消干乱,或压缩干扰;而前馈调节虽可以补偿扰动作用,但它仅能对某个固定扰动进入点而且扰动可以测量出来的干扰进行补偿,这是前馈调节的局限性。一般工业上认为调节系统不受扰动的影响和随动作用为1是比较理想的。所以我们这样来定义理想的调节系统:凡能在理论上符合上面两个指标的调节系统称为理想调节系统。这两个指标是:
First, the question raised At present, the two methods of linear automatic adjustment theory at home and abroad: negative feedback regulation and feedforward regulation. Sometimes in the use of both mechanical combination, but did not change their original features: negative feedback regulation system can not directly offset the interference, or compress interference; feedforward regulation although it can compensate for the disturbance, but it only It is possible to compensate for the disturbance that can be measured by a fixed disturbance entry point, which is a limitation of feedforward regulation. The general industry believes that the unperturbed regulation of the system and the follow-up effect of 1 is ideal. So we define the ideal adjustment system as follows: Any adjustment system that can theoretically meet the above two indexes is called the ideal adjustment system. These two indicators are:
