The present invention provides a fast steering mirror system connected with a universal flexible hinge in a high-precision aim-stabilization system. A set of voice coil motors are taken as drivers to drive the high-frequency motion of a steering mirror; a set of optical grating micrometers are taken as angular position sensors to perform real-time feedback of angular position signals; and a universal flexible hinge bears the scheme of two-degree-of-freedom motion of the steering mirror. The motion features of the steering mirror are employed to design the material composition and structure form of the voice coil motors and the universal flexible hinge so as to solve the compensation problem of the optical system two-level stable loop residual errors on the premise of using the least drivers and the simplest bearing mechanism.
