摘要
Load simulator (LS) is a key equipment for rudder system in hardware-in-loop simulation experiment. In this paper, the present main research results of LS are reviewed. These methods are divided into four kinds based on their mechanism in suppressing "surplus torque/force" and their characteristics are analyzed. The mathematical model of electro-hydraulic load simulator is carried out and the source of "surplus torque" is discussed. A new strategy called "Dual-Loop Control" is proposed to meet some new challenges. Extensive simulation results by means of AMESim confirm that this control scheme results in excellent ability against disturbance, as the same time, with the advantage of simple structure and easy of application.
