Sliding Mode-Based Sensorless Direct Torque Control Applied to Dual Induction Motors-Single Inverter System

Öz

In this paper, the application of Direct Torque Control (DTC) to a single-inverter system driving two induction machines is investigated, incorporating an advanced control strategy. Sliding Mode Control (SMC), specifically the Super-Twisting Algorithm (STA), is employed to replace conventional PI controllers for speed, flux, and torque regulation, overcoming their inherent limitations. Additionally, to eliminate the dependency on physical sensors, a super-twisting-based observer is proposed, enabling accurate estimation of the various quantities required by the control strategy. The system implements cooperative control to synchronize and efficiently manage the operation of the two motors. This technique provides an effective solution to challenges related to robustness in the presence of uncertainties and its ability to rapidly reject disturbances. However, it has some drawbacks, including rapid control actions that can generate vibrations or noise in the controlled system. Simulation results demonstrate that the proposed sensorless DTC-STA control achieves superior performance compared to conventional DTC.

Çift İndüksiyon Motorlu Tek İnvertörlü Sisteme Uygulanan Kayar Mod Tabanlı Sensörsüz Doğrudan Tork Kontrolü

Öz

Bu makalede, Doğrudan Tork Kontrolünün (DTC) iki asenkron makineyi tahrik eden tek invertörlü bir sisteme uygulanması, gelişmiş bir kontrol stratejisi dahil edilerek incelenmiştir. Kayan Mod Kontrolü (SMC), özellikle de Süper Büküm Algoritması (STA), hız, akı ve tork regülasyonu için geleneksel PI kontrolörlerinin yerini almak ve doğal sınırlamalarının üstesinden gelmek için kullanılmaktadır. Ayrıca, fiziksel sensörlere olan bağımlılığı ortadan kaldırmak için, kontrol stratejisinin gerektirdiği çeşitli büyüklüklerin doğru tahmin edilmesini sağlayan süper büküm tabanlı bir gözlemci önerilmiştir. Sistem, iki motorun çalışmasını senkronize etmek ve verimli bir şekilde yönetmek için işbirlikçi kontrol uygular. Bu teknik, belirsizliklerin varlığında sağlamlık ve bozuklukları hızla reddetme kabiliyeti ile ilgili zorluklara etkili bir çözüm sağlar. Bununla birlikte, kontrol edilen sistemde titreşim veya gürültü oluşturabilecek hızlı kontrol eylemleri de dahil olmak üzere bazı dezavantajları vardır. Simülasyon sonuçları, önerilen sensörsüz DTC-STA kontrolünün geleneksel DTC'ye kıyasla üstün performans sağladığını göstermektedir.
