【Abstract】 The paper deals with a new type of configuration of electrohydraulic servovalve with electrical feedback. Experiments show that dynamic perfor-mance of this type of servovalve is good, the bandwidth of this valve is 550Hz at-3db, 307Hz at-90°. Rated flow capacity of servovalve is 10 1/min. This new type of servovalve is a very important element in developing high frequency vibration test stand and high accuracy electrohydraulic control systems. In this paper following problems are discussed: the servovalves with mechanical feedback, influence of different parts upon the behaviour of servovalve, method of compensation, results of experiments etc.更多还原
