【Abstract】 To enhance the vibration suppression effect of flexible satellites, a deployment optimization method of actuators is proposed. Firstly, the attitude dynamics model and vibration model of flexible satellites considering the actuator deployment are established. The actuator deployment optimization problem is redefined from the perspective of control energy and model error, and corresponding optimization criteria are proposed to improve the vibration suppression effect and reduce control energy consumption. Based on the above optimization criteria and the characteristics of the actuator deployment, an improved exhaustive method combining the heuristic algorithm and exhaustive method is proposed to reduce optimization time and improve the accuracy of optimization results. The simulation results show that the prpposed optimal deployment enhances vibration suppression by 96.0% and reduces control energy consumption by 53.2% compared with the existing research.更多还原
