摘要：異步電機無速度傳感器矢量控制系統(tǒng)是目前研究的熱點，本文采用全階自適應(yīng)狀態(tài)觀測器，在傳統(tǒng)的PI自適應(yīng)律的基礎(chǔ)上，加入了模糊自適應(yīng)PI控制策略，對轉(zhuǎn)速進行估計。最后，通過MATLAB仿真數(shù)據(jù)對比，得出改進型的全階自適應(yīng)狀態(tài)觀測器速度辨識系統(tǒng)對電機定、轉(zhuǎn)子電阻變化的魯棒性增強的結(jié)論。 關(guān)鍵詞：全階自適應(yīng)狀態(tài)觀測器；模糊自適應(yīng)；異步電機；PI Abstract: The vector control system of the induction motor speed sensorless is a focus on the current research.
