火箭炮交流伺服系统非奇异快速终端滑模控制

摘要

Aiming at wide variations in moment of inertia, large disturbed moment of a rocket launcher position servo system, a nonsingular fast terminal-sliding-mode control method is presented to achieve finite time convergence of the system,which avoids the singular problem of the conventional terminal sliding mode.Finally, simulation and experimental is performed.The results show that the proposed approach can improve the response speed and accuracy in comparison with the conventional terminal sliding mode control method.%针对火箭炮位置伺服系统转动惯量变化范围大,燃气流冲击力矩强等特点,引入了非奇异快速终端滑模控制方法.通过定义非奇异快速终端滑模面,使该控制方法避免了普通终端滑模的奇异问题,并且具备传统终端滑模有限时间收敛的特性.文中设计了非奇异快速终端滑模控制器,并进行了仿真和实验研究,结果表明:比之传统终端滑模,非奇异快速终端滑模控制方法不仅能够有效提高系统收敛速度,而且具有更高控制精度,适用于火箭炮交流伺服系统高精度控制.
