Parameter Design and Optimization of GMM Servo Valve |

| Abstract: | The parameter design rules were investigated, and the mathematic model and the dynamic simulation model were established based on giant magntostrictive material (GMM) servo valve’s structure.The simulation results uncover that the rule between the main GMM servo valve’s design parameters and dynamic reponse performance, and the stability characteristic; and show that GMM servo valve breadth bandwidth achieves 700Hz based on -8dB stability margin. |
