| Abstract: | Heavy load has two main impacts on the shipborne optical-electric platform. The first one is the decrease of the resonance frequency, narrowing the bandwith of the system, and the second one is the increase of the disturbance. To ensure the precision of stabilization, it needs to improve the torque rigidity of the system and compensate the disturbance. A method is proposed which adds the current loop into the closed speed loop formed by the tachometer, and uses the gyro to get the feedforward compensation o... |
