Performance analysis of different PWM techniques on V/f-based speed control with adjustable boost voltage application for induction motors
This paper presents a comparative study and a method to improveVolt-Hertz (V/f) based speed control of Induction Motors (IMs). Forthis purpose, Sinusoidal Pulse Width Modulation (SPWM) and spacevector pulse width modulation (SVPWM) techniques are investigatedand evaluated, especially from the point of their control performanceon the V/f-based control for three-phase IMs working at different loadand speed conditions. From this aspect, it is a different study from theliterature. Steady and transient effects of both techniques on the abovementioned control methods are analyzed for several case studies.Afterwards, adjustable boost voltage application with modifiedreference commands technique is proposed for both PWM methods inorder to improve start-up performance. All investigations for bothPWM models are carried out under the same conditions. AlthoughSVPWM technique gives more effective results in many cases, theproposed method provides noticeable improvements on SPWM-basedapplications from point of performance on the control method. As anovelty of this study, it is shown that, the bad performance of thecontrol method at low frequency in SPWM application, which haslower computational burden for low cost microcontroller, can beimproved by applying adjustable boost voltage along with modifiedreferences that are proportional to the DC bus current.
Asenkron motorlar için ayarlanabilir gerilim uygulamalı V/f tabanlı hız denetiminde farklı PWM tekniklerinin performans analizi
Bu makale, Asenkron Motorlarının (IM veya ASM) Volt-Hertz (V/f) tabanlı hız kontrolünü iyileştirmek için bir yöntem ve karşılaştırmalı bir çalışma sunmaktadır. Bu amaçla, özellikle farklı yük ve hız koşullarında çalışan üç fazlı asenkron motorların V/f tabanlı hız kontrol performansı açısından sinüzoidal darbe genişlik modülasyonu (SPWM) ve uzay vektör darbe genişliği modülasyonu (SVPWM) teknikleri incelenip değerlendirilmiştir. Bu bakımdan, literatürden farklı bir çalışmadır. Her iki tekniğin yukarıda belirtilen kontrol yöntemi üzerindeki kararlı ve geçici hal etkileri çeşitli örnek durumlar üzerinde analiz edilmiştir. Daha sonra, kalkış performansını artırmak için her iki PWM yönteminde de düzeltilmiş referans komut tekniğine eşlik eden ayarlanabilir yükseltici gerilim uygulaması önerilmiştir. Her iki PWM modeli için yapılan tüm araştırmalar aynı koşullar altında gerçekleştirilmiştir. SVPWM tekniği birçok durumda daha etkin sonuçlar vermesine rağmen, kontrol yöntemi üzerindeki performans açısından SPWM tabanlı uygulamalarda önerilen yöntem dikkate değer iyileştirmeler sağlamaktadır. Bu çalışmanın bir yeniliği olarak, düşük maliyetli mikrodenetleyici için daha az hesaplama yükü olan SPWM uygulamasında karşılaşılan düşük frekansta kötü kontrol performansı, DC hat akımına göre oransal olarak değişen düzeltilmiş referans komutlarıyla birlikte uygulanan ayarlanabilir yükseltici gerilim yöntemi ile iyileştirilebileceği gösterilmiştir.
