Abstract

PURPOSE:To stabilize control speedily from a vibration state by setting a forecasted controlled variable at the time of being in a stable state in an integral term after the end of a limit cycle. CONSTITUTION:When an identification switch 6 is ON, a control block 5 performs ON-OFF control and an identification block 7 inputs the value of a detector 2 and calculates an amplitude and a composite idle time to identify the characteristics of a controlled system 3. A coefficient setting block 8 calculates a PID coefficient from the identified parameters and sets in the control block 5. Then an integral term setting block 9 sets an integral term found from the forecasted controlled variable in an integration buffer after the end of the setting and performs the PID control thereafter with the set PID parameters and the value in an integration buffer. Consequently, the time required for stabilization to the value after the ON-OFF control is shortened.
