Summary:To increase the proximity of a duty-I characteristic to a non-linear element and reduce the occupation of a memory.SOLUTION: The controller includes: a voltage output unit for outputting a voltage instruction value showing an output voltage of an inverter; and a compensation unit for providing the voltage instruction value with a dead-time compensation value which compensates for a dead time of an inverter and calculating at least one of the dead-time compensation value using a function based on at least one of a tanh function and a logistic function.SELECTED DRAWING: Figure 2 【課題】ｄｕｔｙ－Ｉ特性の非線形要素に対する近似性の向上とメモリ占有の削減を図る。【解決手段】 制御装置は、インバータの出力電圧を示した電圧指令値を出力する電圧出力部と、上記電圧指令値に、インバータのデッドタイムを補償するデッドタイム補償値を付与し、当該デッドタイム補償値をｔａｎｈ関数およびｌｏｇｉｓｔｉｃ関数の少なくとも一方に基づいた関数で算出する補償部と、を備える。【選択図】 図２
