摘要:
为避免传统导弹制导和控制系统单独设计存在的缺陷,将两个系统综合考虑,提出一种制导控制一体化设计方法。首先推导出俯仰通道的制导控制一体化数学模型,并化为级联形式;然后引入动态面方法并结合非线性干扰观测器技术,提出了一种基于非线性干扰观测器的积分动态面一体化制导控制系统设计方法,在每一个子系统设计时引入误差的积分项以消除稳态误差,提高了子系统的跟踪精度;采用Lyapunov函数对系统稳定性进行了分析;最后通过仿真验证了所提出的一体化控制算法的有效性。

Abstract:
In order to avoid the defects of traditional design method, which design guidance and control system separately, the two systems are considered together, an integrated guidance and control design method is proposed. Firstly, mathematical model of integrated guidance and control is derived in pitch channel, and converted to cascade form; then an integrated guidance and control design method based on dynamic surface and nonlinear disturbance observer is proposed, integral term is introduced when designing each subsystem to eliminate the steady state error and improve the tracking accuracy. And system stability is analyzed by using Lyapunov function; finally, simulation results verified the effectiveness of the control algorithm.
Key words:  Integrated guidance and control  Dynamic surface  Backstepping
