| 摘 要： | 滑模控制虽然对外部干扰和内部摄动具有不变性，但由于其自身的抖振原因，限制了其在实际工程中的应用．而准滑模控制克服了滑模控制的抖振问题，并对扰动有较强的鲁棒性，因此有广泛的应用．针对天基拦截的非线性模型，考虑到发动机的实际工作特性，基于准滑模控制思想，设计了一种易于工程实现又可控制精度的制导律，并通过数值仿真，验证了该制导律的有效性，并得到了满意的结果．

| Abstract: | The quivering of the variable structure sliding mode control system greatly confines its applications. Pseudo-sliding mode control can solve the problem of the dithering,and it has strong robustness to disturbances. For the nonlinear models of the space interception and actual performance of engines,a terminal guidance law is proposed based on pseudo-sliding mode control theory in this paper. The guidance law is easy to be realized in engineering. Numerical simulation is carried out,and satisfactory results... |
