用于控制电动机的设备和方法
摘要：
本发明涉及用于控制电动机的设备和方法。控制装置将与解算器角度的一个周期对应的360°划分为Z个区域，并判断当前周期中的解算器角度θ是否越过划分边界。当判断为当前周期中的解算器角度θ越过划分边界时，控制装置计算刚好前一个解算器周期中的计算时刻T[n]与当前周期中的计算时刻T之间的时间差ΔT[n]。通过将360°加到在当前周期中获得的解算器角度θ和在刚好前一个解算器周期中获得的解算器角度θ[n]之间的差，控制装置还计算在时间差ΔT[n]的情况下的解算器角度变化Δθ[n]。于是，通过用系数K乘以将Δθ[n]除以ΔT[n]获得的值，控制装置计算旋转速度NM。
摘要（英）：

The invention relates to a control device and a control method for a motor. A control device divides 360 DEG corresponding to one cycle of a resolver angle into Z 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 [Delta]T[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 [Delta][theta][n] with time difference [Delta]T[n] by adding 360 DEG 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 [Delta][theta][n] by [Delta]T[n].
