Abstract

A control law design method for an actively pointing ultra-static platform, firstly determine the structural form, configuration parameters and the number of intelligent flexible actuators of the actively pointing ultra-static platform, and calculate the conversion of the actively pointing ultra-static platform to each intelligent flexible actuator The Jacobian transformation matrix of the expansion and contraction, and then calculate the control law of the active pointing super-static platform, and finally change the control law of the active pointing super-static platform into the control force of each intelligent flexible actuator and output it, so as to realize the control force of the active pointing super-static platform on the load Active vibration isolation and precise pointing adjustment.

Description

technical field [0001] The invention relates to the field of spacecraft control, in particular to a design method for the control law of an active pointing ultra-static platform. Background technique [0002] In recent years, a series of future mission requirements such as high-precision spacecraft represented by very high-resolution earth observation, long-distance laser communication, and space-based astronomical observation, and large flexible spacecraft represented by high-orbit SAR have been proposed. , which puts forward extremely high requirements on the accuracy, stability and agility of the satellite control system. [0003] Limited by the measurement accuracy and measurement bandwidth limitations of traditional attitude sensors (star sensors, gyroscopes), the traditional low-bandwidth attitude control system cannot effectively suppress the influence of various disturbance moments in a wide frequency domain, and only based on satellite attitude control The technica...
