Method and apparatus for hybrid direct-indirect control of a switched reluctance motor

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