Double freedom degree controller

Abstract

Abstract PURPOSE:To specify the optimum value of a double freedom degree coefficient for the integral time by using a target value filter where a primary delay element defining the integral time as a time constant is combined with a controlled system model means. CONSTITUTION:A target value filter means 10 is provided at least with a primary delay element 15 defining the integral time of a PI (proportion and integration) control means 4 as a time constant and a controlled system model means 14 which has a transmission function including the unit transmission function of a controlled system model out of the transmission functions of a controlled system 2. Therefore the means 10 can have a transmission function accordant with the characteristic of the system 2. Thus the optimum value of the double freedom degree can be optimized for the integral time.
