自抗扰三维最优比例滑模导引律设计

Design of the Three-dimensional Optimal Ratio Sliding Mode Guidance Law Based on Auto-disturbance Rejection(ADRC)

针对飞行器末制导过程中存在着模型不确定性因素以及气动环境复杂等鲁棒控制问题,提出一种基于自抗扰三维最优比例滑模制导律控制方案。该控制器能够在线动态反馈补偿内外扰动的影响以增强系统的鲁棒性,仿真结果表明该方案具有较高的制导精度和较强的鲁棒性。

For the existence of model uncertainties and complex environment such as pneumatic robust control problem in the aircraft terminal guidance process,introduce a control scheme based on the optimal ratio of three-dimensional ADRC sliding mode guidance law.The online dynamic feedback controller can compensate for the impact of external interference to enhance the robustness of the system,the simulation results show that the scheme has higher guidance precision and strong robustness.
