THE CONTROL DEVICE OF MOTOR AND THE METHOD USING THE ADAPTATION INTEGRAL BINARY MONITOR AND FUZZY LOGIC CONTROLLER

摘要

A control device of a motor, and a controlling method using an adaptation integral binary monitor and a fuzzy logic controller are provided to perform speed sensorless control of an IPMSM(Interior Permanent Magnet Synchronous Motor) without variation in a PI(Proportional Integral) gain value. A control device(100) of a motor using an adaptation integral binary monitor(170) and a fuzzy logic controller(160) includes a speed indicator(110), a speed controller(120), a current controller(130), a power converter(140), a current detector(150), and the adaptation integral binary monitor. The control device of the motor includes a fuzzification member(161), a regulation based setting member(162), a non-fuzzification member(163), and the fuzzy logic controller. The regulation based setting member extracts a fuzzy control result for a fuzzificated input. The non-fuzzification member performs a decoding operation of expressing information outputted through the regulation based setting member as specific values. The fuzzy logic controller determines an error variation rate and an actual speed after calculating an error between an indication speed and an estimation speed through comparison.
