摘要
A method for vector control of a permanent magnet motor is provided. A torque command is provided from an open-loop observer circuit, which is manipulated to produce an AC voltage command to be applied to a permanent magnet motor. Also provided is a method for utilizing an open-loop observer circuit apparatus. The open-loop observer circuit apparatus takes three-phase inverter pole voltages and uses them to estimate electrical parameters of the permanent magnet motor A method for calculating three-phase inverter pole voltages is also provided, as is used in the open-loop observer circuit. A plurality of voltages are multiplied by the DC bus voltage to calculate the three-phase inverter pole voltages. Finally, a method for estimating electrical parameters is provided, as used in the open-loop observer circuit. Synchronous reference magnetic fluxes and currents are calculated, and these values are used to estimate the electrical parameters.
