摘要： A fault-tolerant position feedback filter may be used in an actuation control system to limit the authority of a first position signal, should the first position signal become erroneous, and thereby prevent a postulated runaway condition of an acuator. The filter includes a difference function, a limited integrator, and a summer. The difference function supplies a first position error signal representative of a mathematical difference between a first position signal and a combined position signal. The limited integrator supplies an integrated position error signal that is limited in magnitude to a predetermined limit. The summer supplies the combined position error signal that is representative of a mathematical sum of the integrated position error signal and the second position signal.

摘要： An electromechanical actuator test system includes an inertia simulator, a first load actuator, a second load actuator, and a test system control. The inertia simulator simulates the inertia of at least a portion of a system that is moved by a test actuator. The first load actuator supplies a first load to the inertia simulator to simulate at least one or more dynamic system loads, and the second load actuator supplies a second load to the inertia simulator to simulate at least one or more steady-state system loads. The test system control supplies the first actuator commands and the second actuator commands.

摘要： An actuator assembly including an actuator housing assembly and a single axis of rotation locking member fixedly attached to a portion of the actuator housing assembly and an external mounting structure. The single axis of rotation locking member restricting rotational movement of the actuator housing assembly about at least one axis. The single axis of rotation locking member is coupled at a first end to the actuator housing assembly about a Y axis and at a 90° angle to an X and Z axis providing rotation of the actuator housing assembly about the Y axis. The single axis of rotation locking member is coupled at a second end to a mounting structure, and more particularly a mounting pin, about an X axis and at a 90° angle to a Y and Z axis providing rotation of the actuator housing assembly about the X axis. The actuator assembly is thereby restricted from rotation about the Z axis.

摘要： A flow control valve assembly, and a method of determining and controlling fluid flow through the valve, that is relatively simple in design, is relatively inexpensive, is accurate, and has a relatively wide measurement range. The flow control valve is relatively compact and includes all of the flow measurement and control components in a single, relatively compact assembly. Such components may include a differential pressure sensor, pressure sensor, a temperature sensor, a position sensor, and a processor. The differential pressure sensor senses differential pressure across the variable area flow orifice. The pressure sensor senses fluid pressure within the valve and supplies a fluid pressure signal. The temperature sensor senses fluid temperature and supplies a fluid temperature signal. The position sensor senses the position of the variable area flow orifice and supplies a position signal. The processor receives the differential pressure signal, the fluid pressure signal, the fluid temperature signal, and the position signal and uses these signals to determine and control fluid flow parameter in the passageway.

摘要： A flight control surface actuation system includes a plurality of smart actuators to move aircraft flight control surfaces between extended and retracted positions. The system includes a high availability network between the flight control avionics and the smart actuators, and between each of the smart actuators. The system configuration allows network nodes associated with each smart actuator to monitor and control one another, under higher level control of the aircraft flight control avionics, to provide multiple levels of health monitoring, control, and shutdown capability.
