Rotor rotating speed/position detecting method of aero-switch reluctance starting/power generator

Abstract

The invention discloses a rotor rotating speed/position detecting method of an aero-switch reluctance starting/power generator. Through coaxially mounting a switched reluctance motor of which the number of teeth is same with that of one selected from a stator and a rotor on the aero-switch reluctance starting/power generator as a position detector, namely a switched reluctance type position detector is coaxially mounted. The position detector realizes estimation for per-unit value of each phase of inductance, thereby acquiring a rotor position signal by means of a correspondence between a phase inductance and a rotor position angle, and supplying accurate and reliable position and rotating speed information for the aero-switch reluctance starting/power generator. The rotor rotating speed/position detecting method of the aero-switch reluctance starting/power generator is suitable for adverse operation environments of high-temperature operation environment, high-speed operation environment, smeary environment, etc. Furthermore the rotor rotating speed/position detecting method of the aero-switch reluctance starting/power generator has advantages of high detecting precision, high reliability, simple structure, high firmness, high stability and relatively low cost of a detecting system, high sensitivity and high efficiency in detecting an output response, and high suitability for position detection in high-temperature and high-speed operation of the aero-switch reluctance starting/power generator.

Description

technical field [0001] The invention relates to a detection method, in particular to a rotor speed / position detection method of an aviation switch reluctance starter / generator, belonging to the technical field of motor signal detection. Background technique [0002] Speed ​​detection is a necessary link to realize the closed-loop control of the speed of the rotating electrical machine. For the control of modern speed-regulating motors such as switched reluctance motors and brushless DC motors, it is not only necessary to detect real-time speed information, but also to detect real-time rotor position information. [0003] For the aviation switched reluctance starter / generator system, real-time and accurate acquisition of rotor speed or position information is a necessary prerequisite to ensure reliable operation and high-performance control of the motor. The position detection of the motor generally detects the rotor position signal by installing a position sensor in the mot...
