PURPOSE:To set automatically parameters of a PID controller by integrating input and output signals to an object system and identifying the object system on a basis of integrated values. CONSTITUTION:A sequencer 16 generates pulses 22-25 in accordance with push- button operations of the operator. Integrators 8 and 19 which receive input and output (u) and (c) of an object system 1 integrate them synchronously with the pulse 25. Both integrated values are supplied to an identifier 14 through A/D converters 11 and 12 and a data buffer 13. The identifier 14 identifies parameters of the controlled system 1 synchronously with the pulse 22. When receiving this result, a control parameter calculator 15 outputs PID control parameters synchronously with the pulse 23, Meanwhile, a test signal generator 17 generates a test signal synchronously with the pulse 24. Thus, parameters of the PID controller are set automatically. |
