According to one or more embodiments, an example system includes a motor, and a motor control system that includes a low side current measurement subsystem. The system further includes a processor that switches the motor control system to use feedforward current control in response to detecting a current measurement failure in the low side current measurement subsystem. The processor further identifies a first phase that has a failed current measurement. The processor also computes a current measurement for the first phase, which has the current measurement failure. The processor further uses the computed current measurement to compute a parameter estimate.
