When electromagnetic valves are applied to flux control in hydraulic models, their slow responses to control signals from microcomputers may result in over adjustment of flux and serious influence on the stability of physical models. In consideration of the above problem, an optimal control algorithm is proposed on the basis of the characteristics of the valves controlled by microcomputers, and softwares are developed. Tests show that the optimal algorithm makes the flux control stable and reliable, and improves the accuracy of physical model test.
