Friction compensation of camera stabilizing device based on velocity estimation
Considering the tracking error caused by friction in camera stabilizing device, a control method of adaptive slide mode is adopted to compensate the friction torque. Furthermore, an improved Eulor method of estimating velocity from position signal is studied in this paper. The application of the two methods in the control system of camera stabilizing device shows that the tracking error caused by friction is weaken effectively, and the methods are also easy to realize.
