应用控制力矩陀螺卫星的事件触发式姿态机动预测控制器设计
Design of Event-Triggered Attitude Maneuver Predictive Controller for Application Control Moment Gyroscope Satellite
摘要
Abstract
In response to the singular phenomena that are prone to occur during attitude maneuvers of the application control moment gyroscope(CMG)satellites,an attitude dynamics equation is established with CMG speed commands as input.The established state space equation is dis-cretized,and optimization calculation indicators are designed.Online optimization calculation of input speed commands is used to minimize torque errors caused by commonly used CMG control laws.A predictive control algorithm based on optimization iteration is designed to provide an atti-tude maneuver feedback controller with a closed-loop structure.In order to reduce the computa-tional burden of online optimization and minimize the number of optimization calculations,a satel-lite attitude maneuver predictive controller with an event-triggered mechanism is designed,the controller can avoid CMG singularity and control satellite rapid maneuver,and effectively reduces the burden of in-orbit calculation on this basis.Through the simulation of the event-triggered atti-tude maneuver prediction controller for rigid body satellites,it is further demonstrated that this controller has the remarkable ability to significantly reduce the online computing burden.关键词
