Özet

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 pulse-width 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.
