| Popis: | This paper proposes a compensation method of common scaling current-measurement error in phase currents for vector control system in AC motor based on current control. The proposed method is compensated for current measurement error using synchronous d-axis integral value in PI controller. By repeating enter twice the current I*q1 and I*q2, the PI controller turns off the switch when it reaches a specific speed, to save the value of the current controller inside the integral term at this time. Using these integral term, the common scaling error is compensated. The feasibility of the proposed method is proved by experimental result. |
