Methods for testing disturbance isolation of EO system

According to the derived calculation formula of disturbance isolation of optoelectronic tracking device,two methods for testing disturbance isolation were given: simulation environment test scheme and platform test scheme. Through analyzing the experimental data of the two testing methods, the advantages,disadvantages and their applications were elaborated.It was pointed out that the bandwidth of speed loop was the key factor to influence the disturbance isolation ability of system under the double-loop control mode. Additional, the optimization solution for control mode of disturbance isolation was suggested to add.
