Aerospace Instrument-Making Annotation << Back MOTION DIFFERENTIAL EQUATIONS OF STEERING ELEMENT OF SCANING OPTICAL-ELECTRONIC SYSTEM PLACED ON MOVING BASE N.N. Vasilyuk The system of motion differential equations of steering flat optical mirror placed in two-axes gimbal is received. The equations connect gimbal’s axis sensors readings, gimbal’s and mirror’s inertia parameters and gimbal’s control torques. Gimbal motion disturbances caused by accelerations and rotations of the base are considered. The algorithm of calculation of masses and coordinates of counterbalances weakening these disturbances is described. Key words: Optical-electronic system, steering mirror, gimbals, motion equation.
