基于自适应滑模控制的自动驾驶仪设计与仿真

摘要

This paper mainly studied the missiles' overload longitudinal autopilot design based on the adaptive sliding mode control theory and finally proved the system's utility with system simulation. The adaptive sliding mode control system is able to provide robust performance to the model with uncertainties and disturbances. So it can be widely used in many fields. In this paper, we introduced the classical proportional - integral autopilot with the adaptive sliding mode structure. Through the simulation analysis, we concluded that the robustness of this system can meet the requirements in practice when random interference exists.%研究弹体纵向过载自动驾驶仪优化控制的设计,为保证系统稳定性,采用具有自适应滑模控制结构的系统对外界干扰具有较强的鲁棒性.以经典的比例-积分结构形式的导弹自动驾驶仪模型为基础,使系统在对外部干扰因素具有一定的鲁棒性,设计并加入了自适应滑模控制结构系统,滑膜控制结构采用开关函数闭环回路结构形式,通过系统仿真分析表明,在存在随机干扰时,系统具有鲁棒性,满足实际工程要求.
