  • Feedback Control In General (AREA)

Abstract

PURPOSE:To improve the quick responsiveness and the control precision by switching the control to the feed forward control and the feedback control alternately at intervals of a prescribed time. CONSTITUTION:Feedback control elements 7 and feed forward control elements 10 are alternately inputted to an operation part 8 which operates a controlled system 8. The shorter this switching time is, the better; but the time required for operation of an operation signal inputted to the operation part 8 is a minimum switching time. While the feedback control is not selected the output of an integral element out of feedback control elements is held. Therefore, a quick response is attained because a large manipulated variable is given in the feed forward control. Meanwhile, the control precision is secured in the feedback control though the response is delayed because the manipulated variable is a relatively small value for the purpose of securing the stability of the control system.
