Control system using internal model cooperative type feedforward method

Abstract

Abstract PURPOSE:To maintain the performance like the disturbance characteristics and at the same time to improve the quick responsiveness to the title system by using a regulator which receives the input of a branch signal having the target value or the reference value. CONSTITUTION:In a control system the feedback value 19 transformed from the control value is compared with the target value or the reference value 1. The deviation value 3 obtained from said comparison is successively added with plural elements 4 of an internal model. Then the outputs of gain controllers 13 and 14 receiving the input of the state value of each element 4 are added together and compared with the feedback value 18 given from a regulator 9. Thus a manipulated variable is defined. In this case, another regulator 9 is newly added between a branch 7 and a gain controller 14 so that a sharp change of the target value or the reference value 1 is bypassed. Furthermore a regulator 10 is added so that the value 3 is bypassed to each element 4. Thus the time lag due to the internal model is eliminated to the change of the target value or the reference value 1.
