Abstract

PURPOSE: To provide a controller suitable for control of a valve having nonlinear opening characteristic by changing proportional and integral gains of a controller according to the valve opening in the control of a control system having a valve as an operation end.
CONSTITUTION: A control unit A' conducts PI operation according to a set point SV and detected values PV sampled at predetermined time intervals, and feeds a differential signal Δϕ of velocity form to a valve Y. To compensate for the nonlinear characteristic of the valve Y, the valve opening ϕ is fed to the control unit A' to change proportional and integral gains.
