Abstract: A method of controlling an electric motor (motor) includes providing a processor having an associated memory storing a stator resistance (Rs) estimation (RSE) algorithm that is programmed to implement the RSE algorithm to execute steps including injecting a current waveform at an arbitrary frame of reference into the stator using a field-oriented-control (FOC) motor controller including an Id controller and an Iq controller, and measuring current and voltage values from the motor responsive to the injecting. The measured current and voltage values are then transformed into transformed current and voltage values in a d/q coordinate system. The transformed current and voltage values are low pass filtered to generate filtered d/q current and voltage values, and a value for Rs is estimated from the filtered d/q current and voltage values. The arbitrary frame of reference can be a time-varying frame of reference.

Abstract: A motor controller architecture and method of operating the same. The motor controller asynchronously generates multiphase control signals for a multi-phase electric motor, relative to the estimation of various state parameters used in generating those control signals. Latency between the state estimation task and the control signal generation task is addressed by storing a timestamp with each input data sample from the sensors, and maintaining that timestamp with the output data from state estimation. Knowledge of the timestamp value allows the control task to update the state estimates to compensate for the time difference between the input data sample and the current sampling period.

Abstract: A motor controller architecture and method of operating the same. The motor controller includes a function for selecting a fractional delay compensation value to be applied in the estimate of rotor position for which pulse-width-modulated drive signals are to be applied to a multi-phase electric motor. The motor is operated over iterated trial values of fractional delay time, while monitoring a magnitude of a feedback signal in the control loop. The selected fractional delay time is that having a lowest magnitude of the monitored feedback signal.
