考虑自动驾驶仪故障的复合全局滑模制导律
Composite Global Sliding-mode Guidance Law Considering Autopilot Failure
摘要
Abstract
In order to improve the precision of tracking low altitude target,the line-of-sight( LOS) angle is needed to be restricted near the Brewster angle to reduce the influence of multipath interference on the detection accuracy of the radar seeker. Based on the principle of global sliding mode control, a global sliding-mode guidance law was designed. This guidance law can make the LOS angle restricted near the Brewster angle in the process of tracking and intercepting the low altitude target. The guidance law can eliminate the stage of approaching the sliding surface,which makes the system equipped with robustness in the whole process. Aiming at the possible failure of the missile autopilot executing guidance command, a virtual command was designed to compensate the failure and disturbance. Combining with the designed virtual command,a composite global sliding mode guidance law was designed. The simulation results show that the composite guidance law can greately improve the anti-interference capability and maintain the stability of the system.关键词
