Active front-wheel steering is the key technology to achieve vehicle handling stability, the quality of its capability has a direct influence on the automobile's stability. In view of the model uncertainty and external disturbance such as sensor noise existing in the steering control process, the present paper utilizes an active steering control of front wheel research grounded in linear matrix inequalities to study sensor noise and mechanical disturbance, etc., and builds a two-DOF vehicle model grounded in yaw and lateral motion. To enhance the robustness of the automobile within nonlinear area, by combining the magic tire model with a two-DOF vehicle dynamics model to describe the non-linearity of tire behavior, a strategy for active steering control utilizing robust $\mathrm{H}\infty$ principles was established, and the active steering control strategy was optimized and solved utilizing linear matrix inequalities to ensure the vehicle's tracking precision and robust stability. Finally, a CarSim/Simulink co-simulation test was established. The designed controller's efficiency and durability have been validated through practical testing.
