PROBLEM TO BE SOLVED: To facilitate analysis and optimal design of signal processing for performing inverse transformation on a stationary coordinate system after performing coordinate transformation on a rotary coordinate system and then performing predetermined processing.SOLUTION: In signal processing, input signals u1(t), u2(t) of a stationary coordinate system are transformed into signals ud(t), uq(t) of a rotary coordinate system and inversely transformed into the stationary coordinate system after performing predetermined signal processing in the rotary coordinate system to generate output signals y1(t), y2(t). Such signal processing is given by a state differentiation equation equivalent with that signal processing, and output signals with respect to input signals are calculated according to arithmetic operation of the state differentiation equation. A, B, C, D are coefficients of the state differentiation equation of a transfer function K(s) for signal processing in the rotary coordinate system. |
