The working principle of the two-axis gyro-stabilized platform for isolating the carrier disturbance is introduced. The mathematical model is analyzed and designed for the stabilized loop of the gyro-stabilized platform. A dual rate-loop control structure is chosen, so the servo system has the better anti-jamming ability and robustness than the single rate-loop control structure. The experimental data from the prototype show that this gyro-stabilized platform has a better stabilized precision.
