摘要： PROBLEM TO BE SOLVED: To achieve uniform short time restart characteristics regardless of the load torque when a synchronous motor is started by suppressing a large speed change occurring after switching from a positioning mode to a synchronous operation mode even if the target rotor position and the actual rotor position are reversed completely in the positioning mode. SOLUTION: In the positioning mode when a synchronous motor is started, the current path of an armature winding is fixed at first and the current is increased gradually to a target value. After the target value is reached, the current path of an armature winding is changed by varying the target rotation angular position little by little as the time elapses, and transition is made to a synchronous operation mode after the motor torque is derived surely and positioning is carried out.

摘要： PROBLEM TO BE SOLVED: To achieve a highly precise position sensorless control of a permanent magnet synchronous motor without depending on a winding resistance value having a large temperature change. SOLUTION: An instantaneous reactive power actual value Q is calculated from a voltage applied to the synchronous motor and a detected current value. An estimated instantaneous reactive power Qhat is calculated from an output angular frequency ω1 of an inverter and the detected current value. The output angular frequency ω1 of the inverter is adjusted so that a deviation ΔQ thereof may become zero. The deviation ΔQ consists of a component proportional to the axis error Δθ of the synchronous motor and a component proportional to the change rate dΔθ/dt of the axis error Δθ regardless of the winding resistance value. Thus, the highly precise sensorless control is realized by a frequency control system which approaches the deviation ΔQ to zero. If it is not instantaneous reactive power, the calculation can be performed without use of the winding resistance value, and an arbitrary value including a function of the axis error Δθ can be used for the calculation.

摘要翻译：要解决的问题：为了实现永磁同步电动机的高精度位置无传感器控制，而不依赖于具有大的温度变化的绕组电阻值。解决方案：从施加到同步电动机的电压和检测到的电流值计算瞬时无功功率实际值Q。根据逆变器的输出角频率ω1和检测到的电流值来计算估计的瞬时无功功率Qhat。调整逆变器的输出角频率ω1，使得其偏差ΔQ可变为零。偏差ΔQ由与同步电动机的轴误差Δθ成比例的分量和与轴误差Δθ的变化率dΔθ/ dt成比例的分量组成，与绕组电阻值无关。因此，通过接近偏差ΔQ为零的频率控制系统来实现高精度的无传感器控制。如果不是瞬时无功功率，则可以在不使用绕组电阻值的情况下进行计算，并且可以使用包括轴误差Δθ的函数的任意值进行计算。版权所有（C）2006，JPO＆NCIPI
