摘要
由于导弹电液伺服机构具有小阻尼、时变性等特点,而且具有不确定性,致使无法得到精确的数学模型。为了保证实际设计过程中控制算法的有效性,采用模糊滑模控制算法。利用Simulink和RTW工具箱,直接在物理硬件上建立实时数字仿真模型,方便快速得到试验结果。实现了对伺服机构的快速半实物仿真,并快速验证了算法的有效性,提高了控制系统的设计效率。
The missile electro-hydraulic servo mechanism has a small damping,changeable and other characteristics,and is uncertain,unable to get the accurate mathematical model.In order to guarantee the control algorithm is effective in the actual design process,the fuzzy sliding mode variable control algorithm was designed for this system.MATLAB has a Simulink and RTW toolbox which can be directly used in the machine based on the physical hardware.The servo mechanism＇s quickly hardware-in-the-loop simulation was finally achieved to verify the effectiveness of the fuzzy sliding mode variable control algorithm and improve the efficiency of the control system＇s design.
