Title: Control method
Inventor: KUMASAKA TORU
IPC: G05B11/36
Filed: 1988-04-30
Abstract: PURPOSE:To ensure the stable and accurate control at an early stage by performing the feedback control only when all controlled variables necessary for acquisition of a manipulated variable are included in a control area. CONSTITUTION:The target value V is set at a setting part 10 and this part 10 transmits a reference input signal r(k) to a comparing part 12. The part 12 obtains an action signal l(k) from a main feedback signal c(k) and the signal r(k) and sends the signal l(k) to a control/operation part 14 which transmits a manipulated variable U(k) through the PID (proportion, integration and differentiation) action control. The part 14 applies the variable U(k) to a controlled system 16 to perform the control so as to secure the coincidence between the value V and the controlled variables Co(k) of the temperature, the pressure, the flow rate, the voltage, etc. These variables Co(k) received from the controlled system 16 are detected by a detecting part 18 and supplied to the part 12 and a comparison control part 20 as the signal c(k). The part 20 compares the signal c(k) received from the part 18 with the control area signal received from the part 10 and applies the PID action signal to the part 14.
