Abstract:
PURPOSE:To shorten the time for adjusting a parameter and to execute the adjustment with high accuracy by providing a judging means for judging data of an estimation process, and executing a correction in accordance with its judgement. CONSTITUTION:A control characteristic analyzing means (first means) 11 calculates a characteristic value, and gives its calculation result to a parameter estimating means (second means) 12. Subsequently, an output of a second means 12 is inputted to a transition output means (fourth means) 14 of an adjustment parameter, a locus of a transition of a parameter of an adjustment process is derived by a fourth means 14, and based on its result, a judgement of an adjustment state is executed by adjustment state judging means (fifth means) 15. As a result of judgement in the adjustment state judging means (fifth means) 15, in the case it is judged that the adjustment is necessary, an adjustment parameter selecting means (six means) 16 executes selection so that the adjustment is executed from the adjustment parameter whose degree of importance is high to a control system. Also, as for other judgement result of the adjustment state judging means 15, the correction is executed by an adjustment correcting means (seventh means) 17. In such a way, the adjustment time is shortened and the accuracy can be improved.
