基于新型非线性函数的动能拦截器自抗扰姿态跟踪控制OA北大核心CSTPCD
Active Disturbance Rejection Control of Kinetic Energy Interceptor Based on Novel Nonlinear Function
针对动能拦截器在开展空间拦截任务时,对姿态控制系统快速性、准确性和鲁棒性的极高要求,提出了一种新型自抗扰控制方法.建立了动能拦截器姿态动力学模型,并将其转换为姿态跟踪误差二阶状态方程;基于自抗扰控制器中小误差大增益、大误差小增益的思想,设计了一种新型的非线性函数;基于该非线性函数,设计了一种新型的跟踪微分器,并且优化了扩张状态观测器和非线性控制器.将指定时间收敛的预设性能函数作为跟踪微分器的期望信号,可实现姿态误差按照预设性能函数收敛到期望值,且…查看全部>>
A novel active disturbance rejection control method is proposed to satisfy the high requirement of speed,accuracy and robustness of attitude control system for kinetic energy interceptor in space interception mission.First-ly,the attitude dynamics model of the kinetic energy interceptor is established and converted into the second-order state equation of attitude tracking error.Secondly,based on the idea of small error,large gain and large error,small gain,a…查看全部>>
