A Control System having Intermittent Compensation Device for Drift of the Primary Detecting Means

概要

To maintain a vary precisely controlled state for a long period of time, drift of the primary means must very carefully be compensated. A sampled data control system with finite pulse width can advantageously be utilized in such control system as stated in the title, using a PI controller. The sampling period T must be taken as small as possible within the required limit of the length. However, if drift of the primary detecting means contains considerable amount of high frequency components, T must not take a value near the period of such frequen cy components. It is proper for selecting such pulse width h that the ratio h/T takes the value in the range from 0.4 to 0.6.
