摘要
针对制导炮弹模型中的非线性和耦合性,提出一种基于过载的制导炮弹非线性控制系统设计方法,建立了炮弹的过载时变模型,在俯仰和偏航通道控制器设计过程中加入了一阶低通滤波器,消除了"计算膨胀"的难题,并通过非线性阻尼项消除外界扰动,最后由Lyapunov理论证明了系统是半全局域渐近稳定的,能准确跟踪指定过载。
A novel nonlinear control designed is proposed in the presence of guided projectile with nonlinear and coupling. Nonlinear timevarying model of guided projectile is established,a firstorder lowpass filter is added in the pitch and yaw channel controller to avoiding the problem of “computing expansion”. The external disturbances is eliminated with the nonlinear damping items and the tracking error is proved to converge to a small neighborhood around zero by the Lyapunov stability theorem. Last,system is proved by simulation with Matlab.
