  • Position and speed synchronization for a dual linear actuator flap system
    Patent number: 9899940
    Abstract: A method for controlling a first motor and a second motor to synchronize respective positions of the first motor and the second motor may comprise comparing the positions to determine a position difference, incrementally increasing a speed of one of the first motor and the second motor and incrementally decreasing a speed of the other of the first motor and the second motor according to the position difference, and repeating the incrementally increasing and incrementally decreasing until the respective positions are synchronized. Additionally, motor current limiting may be applied by reducing the target speed of the motor(s) with high applied torque(s), which may result in a position difference between the two motors subject to synchronization/correction. If current limiting is applied to one or both of the motors, speed synchronization may be applied in addition to position-based synchronization.
