Title:
モータの制御装置および制御方法
Document Type and Number:
Japanese Patent JP5456608
Kind Code:
B2
Abstract:
A control device divides 360° corresponding to one cycle of a resolver angle into N zones, and determines whether or not a resolver angle theta in the current cycle exceeds a division border. When determined that resolver angle theta in the current cycle exceeds a division border, the control device calculates a time difference DeltaT[n] between a calculation time T[n] in the immediately preceding resolver cycle and a calculation time T in the current cycle. The control device also calculates a resolver angle variation Deltatheta[n] with time difference DeltaT[n] by adding 360° to the difference between resolver angle theta obtained in the current cycle and a resolver angle theta[n] obtained in the immediately preceding resolver cycle. The control device then calculates a rotation speed NM by multiplying, by a coefficient K, a value obtained by dividing Deltatheta[n] by DeltaT[n].
