To control a controlled system under smooth change of manipulated variable even if an objective value is suddenly changed by adding a delay element to a fixed operating element under characteristics other than the dead time characteristics of the controlled system. ! An operator 11 subtracts a main feedback signal 103, a control variable, from an objective value 101 and a subtractor 12 also subtracts a local signal 105 from the subtracted result of the operator 11 to output a control deviation signal 104. A main controlling element 13 consists of a PID operating element 131 fixed by the characteristics other than the dead time characteristics of a controlled system 2 and a primary delay element 132 and converts the control deviation signal 104 at its characteristics to output a manipulated variable 106. A local feedback element 14 converts the manipulated variable 106 at its characteristics to output the local feedback signal 105 to the subtractor 12. ! (C)1983,JPO&Japio |
