Abstract
Hareketli yük taşıma ekipmanına yönelik bir akışkan gücü kontrol sistemi, aktüatörlerin senkronize veya senkronize olmayan ilgili pozisyonlarının seçici şekilde elde edilmesi amacıyla senkronize olmayan ilgili hızlarda birlikte işlev gösteren ilgili yük kavrama elemanlarının seçici şekilde birbirine doğru veya birbirinden uzağa doğru, veya ortak bir yönde hareket ettirilmesine yönelik bir çift hidrolik aktüatör içermektedir. Aktüatörler, bir kontrolörün bunların ilgili hareketlerini izlemesini ve ilgili kasıtlı pozisyonlar, hızlar veya hız değişimi oranlarındaki kasıtsız farklar gibi aktüatörlerin ilgili hareketlerindeki kasıtsız farkların düzeltilmesini sağlayan sensörlere sahiptir. Kontrolöre yanıt veren ilgili hidrolik valfler, aktüatörlerin kasıtlı ile ilgi hareketlerinden farkların daha doğru ve hızlı şekilde düzeltilmesi için ilgili aktüatörlerden ilgili akışları ayrı ayrı veya eş zamanlı olmayacak şekilde azaltmaktadır.
