A method of controlling an electric motor includes determining a PWM control signal, analyzing the PWM control signal to determine if components of the PWM signal are within a threshold amount of each other, applying duty-cycle blanking to the PWM control signal, if the components of the PWM control signal are within the threshold amount of each other, to generate an adjusted PWM control signal, and controlling the electric motor with the adjusted the PWM signal to limit parasitic effects.

Motor control system, controller, and method

An electronic control architecture for an aircraft actuation system may include a first channel and a second channel. The first channel may be configured to receive one or more inputs comprising a movement command, to produce an output to control a component of the system, and to receive feedback from the component respective of movement of the component. The first channel may comprise a fault detection module configured to compare the feedback to the command to determine if the first channel is functioning properly. The second channel may be configured to receive the one or more inputs and, if the first channel is not functioning properly, to produce an output to control the component.
