A novel hybrid control strategy for potential energy regeneration systems of hybrid hydraulic excavators

摘要: Excavators as a kind of typical construction machinery are widely used in all kinds earthworks. Due to the low efficiency excavator, many enterprises and researchers have been committed improving its efficiency. Energy regeneration system is an effective energy-saving technology, which has attracted much attention recent years. However, traditional energy pays saving, while maneuverability not fully considered. This article focuses on saving hybrid hydraulic excavator boom. A novel control method guarantee dynamic performance system, based electrical potential proposed. combined use torque controller for permanent-magnet synchronous machine position proportional pressure valve makes insensitive ...
