摘要: A positioning system includes an actuator, valve (preferably pneumatic), position sensor and an electronic valve controller, integrated in a single unit. Continuously variable setpoints are possible within the range of operation. A preferred control circuit includes a signal converter, a ramp generator to smooth the shape of the command or target value signal applied, a position feedback sensor to report the actual position of the actuator, a controller, and a driver, containing an H-bridge, for controlling the pneumatic valve which feeds air into the actuator mechanism. Integration of all these components into a single unit shortens signal paths, improves resistance to electrical noise, and permits faster response time.

摘要: In order to provide proportional control of a poppet valve or a gate valve, adapted for fluid power applications, an electrical voice coil is used to move the gating element. Further, a preferred embodiment includes a feedback means for detecting and regulating the position of the gating element, for example to compensate for any perturbing mechanical vibrations. The result is a valve which closes securely, is infinitely variable within a range, and can make up to a full stroke, from fully closed to fully open, within 3 to 10 milliseconds, compared to the 15 milliseconds needed by a solenoid. Due to its fast response time, the improved valve mechanism provides much faster tracking of any changes in an applied command signal. Suitable applications are mechanical testing devices, and other repetitive motions situations, such as industrial automation and animatronics.
