本文提出了一种采用变量泵的新型电动液压执行器（new EHA），以提高电动液压执行器的动态响应。该系统结合了电动系统和液压系统的优点，易于与整个电气系统集成，是节能和提高控制性能的一个有前途的趋势。首先介绍了EHA的基本原理及其与传统EHA的区别。并建立了数学模型。然后，利用模糊算法设计了控制器。最后，对新EHA进行了仿真和实验研究，结果表明了新EHA的有效性。
In this paper, a new type Electric Hydraulic Actuator(New EHA) adopted variable displacement pump is presented to enhance the dynamic response of EHA. This system combines the advantages of electric with hydraulic systems and it is easy to be integrated with the whole electric system, which is a promising tendency to save energy and enhance control performance. Firstly, the basic principle and the difference with the traditional EHA are introduced. Moreover, the mathematical model is constructed. Then, the controller by using the fuzzy algorithm is designed. Finally, the simulation and experiment for the New EHA are investigated, both of the results show the effectiveness of the New EHA.
