Simulation Study on the Guidance Law of UCAV Based on Sliding Mode Variable Structure
摘要
Abstract
In order to improve the stability of the guidance law control of UCAV, the guidance law control method of sliding mode variable structure is adopted.According to centain assumptions, the three degree of freedom model for UCAV is established, and the actual flight trajectory is obtained based on the motion model and the initial state.The expected trajectory of UCAV is obtained based on sliding mode variable structure guidance law, and the control is driven by the error between the actual trajectory and the expected trajectory.The simulation results show that the control states vary smoothly in the control process of guidance law, and the validity and rationality of the proposed method are verified.关键词
