Abstract: This paper presents the fundamental approaches of modeling thermal-hydraulic component briefly. A set of lumped parameter mathematical models is developed, which are based on conservation of mass ...

Abstract: High accuracy tracking control of direct current (DC) motors is concerned in this paper. A continuously differentiable friction model is adopted to account for the friction nonlinearities, which allows more flexible and ...

Abstract: Energetic macroscopic representation (EMR) is an effective graphical modeling tool for multiphysical systems, and EMR model clearly illustrates the power flow and interaction between different subcomponents. This paper ...

Abstract: An electrohydraulic load simulator (EHLS) is a typical case of torque systems with strong external disturbances from hydraulic motion systems. A new velocity synchronizing compensation strategy is proposed in this paper ...

Abstract: High flow rate electrohydraulic servo valve is widely applied in hydraulic servo systems. Typical high flow rate servo valve is threestage nozzle flapper pilot structure which is complicated, unreliable, and highly costly. ...

Abstract: In order to provide a solution of active rectification for linear pumps in pump control system, a novel collaborative rectification structure is conceptually designed in this paper. The fundamental subsystem is the direct ...

Abstract: Electro-hydraulic load simulator (EHLS) is a typical closed-loop torque control system. It is used to simulate the load of aircraft actuator on ground hardware-in-the-loop simulation and experiments. In general, EHLS is ...
