模糊线性/非线性自抗扰切换控制及其应用

针对干扰弹在作战过程中所遇到的强非线性的干扰、模型不确定性的影响等特性，提出了一种模糊线性/非线性自抗扰切换控制器。首先，以干扰弹滚转运动模拟装置为研究对象，分别建立了以飞轮角速度为被控量、滚转角为被控量的数学模型；提出了用模糊规则改进线性/非线性自抗扰切换控制条件，进而实现更为平稳的模糊软切换；然后选择采用飞轮角速度线性自抗扰控制内环和滚转角模糊线性/非线性自抗扰切换控制外环的双闭环控制策略；最后，搭建了系统的仿真模型与实验平台。仿真与实验结果都表明该控制器兼具了线性自抗扰与非线性自抗扰的优势，具有较高的实际应用价值。

Fuzzy linear/nonlinear active disturbance rejection switching control and its application

A fuzzy linear/nonlinear active disturbance rejection switching controller is proposed to deal with the strong nonlin-ear interference and the influence of model uncertainty encountered by the jamming bomb in the combat process. Firstly, mathematical models with the flywheel angular velocity as the controlled variable and the rolling angle as the controlled variable are established for the roll motion simulation device of the jamming projectile. The fuzzy rules are used to improve the linear/nonlinear active disturbance rejection switching control conditions, so as to achieve more stable fuzzy soft switching. Then, the strategies of the closed inner loop of Active Disturbance Rejection Control (ADRC) of flywheel angular velocity and the closed outer loop of fuzzy linear/nonlinear active disturb-ance rejection switching control of roll angle are used. Finally, the simulation model and experimental platform of the system are built. The simulation and experimental results show that the controller has the advantages of linear and nonlinear ADRC, and has high applicability.
