Based on the design process of a TV guidance header, the mechanical structure constitution, main components selection and software and hardware realization were introduced. The disturbance-isolation theory of the stabilized platform was analyzed and the control structure including multiple closed-loops was designed. Each part of the control system was modeled, and then by simplifying their equations, the whole system model was founded and the control method was designed according to the frequency domain analysis method. To eliminate the gyro’s noise signal, a wavelet threshold filter was proposed, which can depress the feedback noise signal effectively a
