    摘要： Position and speed correction are applied to observed values from a position sensor in order to operate an electric motor. Observed position values and observed speed values are obtained from the position sensor for time points during a sampling window, ideal position values and ideal speed values are determined for each of the time points, and position and speed error values are determined based on the observed and ideal values. Stored position information is updated using the position error values and the speed error values. The electric motor is operated using corrected position values and corrected speed values that are determined from the observed position values, the observed speed values, and the stored position information.

    摘要： In accordance with exemplary embodiments, rotor temperature estimation is provided for estimating rotor temperatures of an electric motor in an electric vehicle. A method comprises estimating a rotor temperature in a controller for an electric motor of a vehicle using a fast-mode rotor temperature estimator for a time interval, and then deactivating the fast-mode rotor temperate estimator after the time interval and activating a normal-mode rotor temperature estimator in the controller for the electric motor of the vehicle. A system comprises an electric motor, a resistance rotor temperature estimator including a limit value limiting a temperature estimate increase for temperature estimates, and a controller for the electric motor, which uses the temperature estimate and is configured to temporarily increase the limit value of the resistance rotor temperature estimator providing a fast-mode rotor temperature estimate.

    摘要： A method of processing a resolver fault in a motor generator unit (MGU) includes receiving a position signal from a resolver describing a measured angular position of a rotor of the MGU, determining the presence of the resolver fault using the position signal, and calculating or extrapolating an estimated rotor position when the resolver fault is determined. A predetermined resolver fault state may be determined using a measured duration of the resolver fault, and the MGU may be controlled using the estimated rotor position for at least a portion of the duration of the resolver fault. A motor control circuit is operable for processing the resolver fault using the above method, and may automatically vary a torque output or a pulse-width modulation (PWM) of the MGU depending on the duration of the resolver fault.

    摘要： In a motor controller, a modified interpolation technique uses an extrapolated torque command for the upper table to improve torque linearity under certain conditions. When the torque command input is greater than the max torque limit of a first look-up table, but less than the maximum torque limit of a second, adjacent look-up table, the desired current command is computed by interpolating between the maximum torque limit of the first table and a revised torque value for the second look-up table, wherein the revised torque value is determined by extrapolating from the maximum torque limit of the first look-up table through a torque value based on the torque command input.
