Embodiment Construction
[0065] A synchronous control method for a two-axis follow-up system of a space optical remote sensor according to the present invention will be further explained and illustrated below in conjunction with the accompanying drawings.
[0066] The control principle of the inventive method is as figure 1 shown. Firstly, the scanning period T of the spindle motion system of the controlled mechanism and the effective scanning angle of view θ r , scan efficiency η, plan the motion curve of the main shaft, and obtain the reference angle θ of the main shaft at time t * (t), the spindle system is driven by a digital control method to move according to the position command signal; at the same time, according to the rotational speed ratio k of the spindle system and the follower shaft system, the position signal after the proportional transformation is obtained as the position command signal of the follower shaft system, The servo system is driven by the digital control method to comple...
