摘要： A rotary actuator (10) includes a pole riser (24) that acts as a mechanical stop and provides advantageous magnetic latching features, which overcome the problems typically associated with the end of travel in conventional rotary actuators. The pole riser designed in accordance with this invention includes a necked region (70) of reduced cross-sectional area, which allows for an air gap to be maintained between at least a portion of the pole riser (24) and the rotor pole at the end of travel. The pole riser necked region provides an additional flux pathway ( PHI s) that is magnetically saturated and the remainder of the pole riser provides a magnetic pathway for a latching flux ( PHI L), which maintains the rotor in an end of travel position without requiring an increase in the current through the coil. A rotary actuator design and control methodology are disclosed.

摘要： A device for controlling a 4-phase 8-stator pole/6 rotor pole switched reluctance machine includes a microcontroller, a converter circuit for energizing the stator windings of the switched reluctance machine, four Hall sensors adapted to detect rotor position to a resolution of 15 mechanical degrees, a phase current sensor, and a phase voltage sensor. The controller is programmed to implement a rotor position estimator for generating an estimated rotor position signal corresponding to the position of the rotor. The estimator is implemented using an observer-based state variable motor model, and is responsive to the measured phase voltage, the measured phase current, and the transitions generated by the Hall sensors. The estimated rotor position signal is determined by running the observer model in parallel with the physical motor. The observer uses a phase current error signal, and a position error signal generated using the low resolution position transitions, to force the estimated rotor position state variable to converge. The generated estimated rotor position signal is substantially continuously-valued and is used by a commutation means programmed in the controller for controlling commutation of the machine phases.
