Title The Design and Simulation of Electro-hydraulic Servo Valve Drive Circuit
Abstract
This paper mainly describes the design and simulation of electro-hydraulic servo valve drive circuit. Drive circuit mainly consist of nulling circuit, current limit circuit, preamplifier circuit, power amplifier circuit and flutter signal circuit. According to the requirements, this paper focuses on the two parts of the power amplification circuit and preamplifier circuit of the drive circuit design and simulation, and use Multisim10 for the simulation of the circuit. The paper focuses on the principle and the calculation process of component parameters about the electro-hydraulic servo valve driving circuit. On all circuit design is completed, to combine two circuits, again use software for simulation, the results with paper and theoretical calculated values conform to the requirements, can achieve the goal of control of electro-hydraulic servo valve.
