The opto-electric servomechanism (OES) plays an important role in obtaining clear and stable images from airborne infrared detectors. However. the inherent torque disturbance and the noisy speed signal cause a significant decline in the inertial stability accuracy and low-speed performances of OESs. Traditional linear control schemes cannot deal with the nonlinear torque disturbance w... https://foldlyers.shop/product-category/medium-duty/
