Application of Acceleration Feedback Techniques on Inertial Stabilization Platform

The performance of the inertial stabilized platform will be affected heavily by inner or outer factors, which will change the transfer characteristic of the inertial stabilized platform and result in the degradation of the precision of the system. Therefore, the high-gain acceleration feedback will be inserted in the velocity feedback loop to compensate the change of these factors. And the acceleration feedback loop can stabilize the platform because that the accelerometers are inertial sensors, the active disturbance suppression of the platform is the product of the error attenuation of the acceleration loop and the velocity loop. Extensive experimental results show that the acceleration feedback can enhance the active disturbance suppression of the platform.
