交流电动机控制设备
摘要：
当切换区域为A1时(即步骤S10中的“A1”)，控制设备以由反馈计算根据转矩差计算的相位变化量提前相位(步骤S20)。另一方面，当切换区域为A1之后的A2时(即步骤S10中的“A2”)，控制设备以步骤S20中提前的相位变化量滞后相位(步骤S30)。另外，当切换区域为A2后的A3时(即步骤S10中的“A3”)，控制设备以步骤S20中提前的相位变化量再度提前相位(步骤S40)。
摘要（英）：

When a switching area is A1 (namely ''A1'' in S10), a control device advances the phase for a phase change quantity which is comuputed through feedback computing according to a torque difference (Step S20). On the other hand, when the switching area is A2 (namely ''A2'' in Step S10) after A1, the control device delays the phase with the phase change quantity advanced in the step S20 (Step S30). Additionally, when the switching area is A3 (namely ''A3'' in Step S10) after A2, the control device advances the phase with the phase change quantity advanced in Step S20 again (Step S40).
