Abstract

In this study, in order to improve dynamic performance of variable speed Permanent Magnet Synchronous Generator (PMSG) drive system and obtain a speed (mechanic) sensorless operation, a second order sliding mode controller together with a hybrid observer are proposed. In the presence of instantaneous speed change and disturbance effects such as parameter and load torque deviations, it is aimed at developing a robust speed response against all uncertainties without using a mechanical sensor in the drive system. In controlling PMSG, a second order sliding mode observer and a simple Kalman Filter, hybrid structure, are utilized in view of their simple observer-controller structure. Thanks to this the structure, chattering effect, one of the important disadvantages of classical sliding mode observer-controller structure, is reduced and a good dynamic speed response is yielded in variable speed operation. Results are compared to classical sliding mode and differences between the hybrid observer-controller and the classical system are revealed.

Özet

Bu çalışmada, Sabit Mıknatıslı Senkron Generatör (SMSG) sürücü sisteminin değişken hızlarda dinamik cevabını iyileştirmek ve hız (mekanik) sensörsüz çalışma sağlamak için hibrit bir gözlemleyici ile birlikte ikinci dereceden kayan kipli hız denetimci beraber önerilmektedir. Önerilen denetim sisteminde, anlık hız değişimi ve parametre değişimleri gibi bozucu etkilerin var olduğu durumlarda, sürücü sisteminde mekanik sensör kullanılmadan dış bozucu etkilere karşı dayanıklı hız cevabının elde edilmesi amaçlanmaktadır. SMSG’ün denetiminde, gözlemleyici-denetleyici yapısının basit ve uygulanabilirliğinin kolay olması amacıyla ikinci dereceden kayan kipli gözlemleyici (üstün burulma algoritması) ve basit bir Kalman Filtresi yapısı kullanılmaktadır. Bu sayede, klasik kayan kip gözlemleyici-denetimci yapısının önemli dezavantajlarından biri olan çatırdama etkisi azaltılmakta ve hız referansı değişimlerine karşı iyi bir dinamik hız cevabı elde edilmektedir. Sonuçlar, klasik kayan kip gözlemleyici yapısı ile karşılaştırılmakta ve aralarındaki farklar gösterilmektedir.
