Abstract

In this study, the open loop and closed loop behaviours of a pulse-width modulated electro-hydraulic system are investigated theoretically. First a mathematical model is formulated for the system and methods for obtaining system responses to pulsewidth modulated inputs are developed. Using these methods, the responses of the open loop and closed loop hydraulic systems to pulse-width modulated step, periodic and aperiodic inputs are calculated. Effect of pulse frequency on the system response is investigated.

Özet

Bu çalışmada, puls genişliği modülasyonlu elektrohidrolik bir servo sisteminin açık ve kapalı çevrim davranışları teorik olarak incelenmiştir. İlk olarak sistemin matematiksel modeli kurulmuştur. Daha sonra sistemin puls genişliği modülasyonlu girişlere cevabını bulmak için metotlar geliştirilmiştir. Bu metotlar kullanılarak, puls genişliği modülasyonlu basamak, periyodik ve periyodik olmayan girişler için açık ve kapalı çevrim sistemlerin cevapları bulunmuştur. Puls frekansının sistem cevabı üzerindeki etkisi incelenmiştir.
