基于动态逆和变结构控制理论的BTT导弹控制系统设计

The Design of Control System Based on Dynamic Inversion and Variable Structure Control Theory Applied to BTT Missile

基于动态逆和变结构控制理论提出了一套设计BTT导弹控制系统的方法。该方法首先应用动态逆控制对被控对象近似线性化,再应用变结构控制提高系统的鲁棒性。文中详细推导了基于气动参数上下界的控制系统参数选择方法,无需对气动参数在线辨识。最后,在考虑各个环节非理想因素的情况下,针对某型BTT导弹进行了三通道联合仿真,证明了方法的有效性。

A new method of designing control system based on dynamic inversion （ DI） and variable structure control （ VSC ） applied to BTT missile is presented . In this method, DI is employed to linearzing the nonlinear model of the missile. The controller must be capable of attenuating disturbances, then the robustness of system is improved based on VSC, the principle of choosing parameters of controller is deducted based on the bounds of aerodynamic derivatives withont the aerodynamic derivatives identification online. In view of all the factors that are not ideal, three channel simulation with a BTT missile proves that the method is effective.
