PROBLEM TO BE SOLVED: To efficiently manage the regeneration of an electric motor.SOLUTION: An instantaneous voltage 214 supplied from a power supply 205 to a motor 202 is determined by using a voltage signal 213 received from a voltage sensor 210. A new average voltage 216 of the motor 202 is calculated using the instantaneous voltage 214, an average voltage 218 calculated the previous time and a weighting coefficient 220 of the instantaneous voltage 214. The difference 222 between the new average voltage 216 and the instantaneous voltage 214 is compared with a prescribed threshold 224, and it is determined whether there is occurring a regeneration state 226. If it is determined that the regeneration state 226 is occurring, driving of the motor 202 is controlled so as not to reduce a duty cycle 228 of the motor 202.SELECTED DRAWING: Figure 2
【課題】電動モータの回生を効率的に管理すること。【解決手段】電源205からモータ202に供給される瞬時電圧214が、電圧センサ210から受信する電圧信号213を用いて特定される。瞬時電圧214、前回算出した平均電圧218及び瞬時電圧214の重み係数220を用いて、モータ202の新たな平均電圧216が算出される。新たな平均電圧216と瞬時電圧214との差分222を所定の閾値224と比較して、回生状態226の有無が判定される。回生状態226が発生していると判定されると、モータ202のデューティサイクル228が低下しないようにモータ202の駆動が制御される。【選択図】図2
