Year: 2025
Type: conference-paper
Abstract: Hydraulic systems are widely used in almost all industries. However, a significant drawback of hydraulic systems is large energy loss. One of the main reasons is the improper power design that causes excessive energy consumption by generating heat in the system, which reduces the equipment's lifespan and increases operating costs in production. In this study, we propose a power control system for hydraulic systems using servo control valves. The hydraulic station consists of a fixed displacement pump driven by an AC servo motor, which is controlled to change speed based on the feedback pressure from the load in order to control the pump's output power, thus also controlling the overall power of the system. The study begins with the proposal of the hydraulic system, followed by model establishment, simulation, experimental implementation in the workshop, and evaluation. The initial research results show that the system is capable of controlling power, improving energy efficiency, and ensuring the accuracy of the motion of actuator.
