拦截高速机动目标的动态终端滑模制导律设计
Guidance law based on dynamic terminal sliding mode for high speed and maneuvering target
摘要
Abstract
A design scheme of robust guidance law based on dynamic terminal sliding mode control was proposed for the inter-ception of new high speed and maneuvering targets. Firstly, based on the characteristics of finite time convergence of the dynamic terminal sling mode control, a terminal sliding mode switching function with compensating factor was studied,by which a non-linear sliding mode super-surface was proposed through differentiation element then. Finally, the guidance law based on dynamic terminal sliding mode was designed,and its characteristics of finite time convergence were analyzed. The new guidance law not only has the character of finite time convergence,but also is designed based on the derivative of the command acceleration,which could transfer the discrete term that is common in sliding mode control into the first-order derivatives of the guidance law,and remove the chatte-ring problems. Simulation results show that the proposed guidance law could guarantee the missile's line-of-sight finite time conver-gence and has better robustness and guidance precision.关键词
