  • 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.

  • ENGINE INTAKE AND EXHAUST FLOW MANAGEMENT
    Publication number: 20180045109
    Abstract: An engine system including a power plant, an intake assist device connected to an air inlet of the power plant, and an expander connected to an exhaust outlet of the power plant is presented. A motor/generator is connected to power the expander to selectively provide power to and capture power from the expander. An expander controller is connected to control the motor/generator connection to the expander, and is configured to select between a passive mode, where exhaust passively moves through the expander, and an active mode, where the motor/generator powers the expander to actively draw exhaust from the exhaust manifold. In one example, the air intake and exhaust flows are controlled independently of the rotational speed of the power plant.
