<p>PURPOSE:To obtain an identification arithmetic unit of a control parameter where the influence of noise is reduced and the identification precision is improved, by weighting the control parameter with a weight coefficient to identify the control parameter. CONSTITUTION:A control system consists of a control system 1 and a device 2 to be controlled, and an identification arithmetic unit 7 to which an input value U(k) and an output value Y(k) of the control system 1 are inputted to obtain an arithmetic output is provided. The input value U(k) and the output value Y(k) of the control system 1 as the identification object are inputted to an identification computing element 3 to obtain an operation output 4. The input value U(k) and the output value Y(k) are inputted to an excitation condition decider 5 also, and the excitation condition decider 5 decides an excitation condition on a basis of these values. A decided level signal from the excitation condition decider 5 is inputted to a weight coefficient generator 6, and a weight coefficient (m) is calculated on a basis of this signal. The weight coefficient (m) is inputted to the identification computing element 3, and the control parameter which controls the control system 1 is weighted to obtain the arithmetic output 4.</p> |
