【発明の名称】制御系の汎用性時間差比較補償方法及び装置
Document Type and Number:
Japanese Patent JP2716437
Kind Code:
B2
Abstract:
A versatile time difference comparison compensation method of a control system, wherein a desired value or a reference value of feedback control is branched into several parts. One of the branches is directly compared with a feedback variable to obtain a first difference value and lag elements having various delay times are connected to the other of the branches, respectively, in order to make time difference comparison between the desired value or the reference value and the feedback variable to obtain second and third difference quantities, respectively. Various weighting elements receive the difference quantities inclusive of the first difference quantity to put various weights to the difference quantities and to obtain signals and the sum of the resulting signals is then calculated and the signal obtained by the sum is passed through a gain adjustment element to re-adjust a gain adaptive to a controlled system to produce an operation quantity. Feedback control is provided by compensating for the response delay of the controlled system by utilizing the time difference comparison between the desired value or the reference value and the feedback variable that has not been used conventionally, and can thus be adapted to all kinds of control equipment and control system with analog control and digital control.
