Abstract:
A method of operating an electromechanical actuator (EMA) system includes determining a command time remaining for an actuator to attain a commanded position and determining a stop time required to stop movement of the actuator. The command time is compared to the stop time, and an electric motor driving the actuator is decelerated if the stop time is equal to or greater than the command time. An electromechanical actuator system includes an actuator and an electric motor operably connected to the actuator, the electric motor configured to drive movement of the actuator. A controller is operably connected to the electric motor to control operation of the actuator. The controller is configured to determine a command time remaining, determine a stop time, compare the command time to the stop time, and decelerate the electric motor if the stop time is equal to or greater than the command time.
