    摘要： A method includes detecting a first event and executing a first procedure to identify a sensor offset in response to detecting the first event. The method further includes determining, via a computing device, whether the sensor offset was measured during the execution of the first procedure, scheduling a second procedure to execute in response to detecting a second event if the sensor offset was not measured during the first procedure, and scheduling the first procedure to execute in response to detecting a subsequent occurrence of the first event if the sensor offset was measured during the first procedure.

    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.

    摘要： Methods, apparatus, and systems are provided for regulating the operation of a drive system within a battery voltage and power range. The apparatus includes a PI regulator producing a signal for regulating a torque output of the drive system based on a DC voltage source limit and/or power limit, a converter normalizing the signal from the PI regulator to produce a new torque limit, and a switch selecting either the new torque limit or an available torque limit of the drive system. The PI regulator includes an integrator having an initial value based on the torque output of the drive system and a copper loss term.
