Abstract
In order to improve the dynamic response bandwidth of three-stage electro-hydraulic servo valve, a new method, speed-feedback control is presented in this paper. The construction and principle of three-stage electrohydraulic servo valve are explained, and the mathematical model of three-stage electro-hydraulic servo valve is built in frequency domain. Experimental and simulation results show that the bandwidth compared with proportional control is improved under speed-feedback control. Moreover, the research results play an important role in developing high performance three-stage electro-hydraulic servo valve.
