The ACT system model of red high-definition optical pickup is the basis of servo system design, using GLFF （generalized linear feedforward network） for their modeling and simulation studies, and the control model of the system, control program and test control algorithms can be established before the hardware solutions implemented. In this paper, on the basis of the theoretical modeling,GLFF approximation method is used to establish the actual model, through the experimental comparison to determine their model, and completed the ACT system model of the red high-definition optical head and simulation analysis. It provides the applicable control model for the design of servo system.
