深弹舵机电动加载系统的滑模模糊自适应控制研究

针对某型深弹舵机电动加载控制系统存在跟踪精度、参数不确定性和干扰问题,将滑模变结构与模糊自适应控制相结合,设计了一种滑模自适应控制方案。在滑模控制中引入自适应参数调节律和模糊控制规则,采用自适应律实时调节控制器,采用模糊控制消除抖颤。仿真结果表明,滑模模糊自适应控制方法不仅改善了舵机电动加载系统的跟踪精度,而且还有效地消除外界干扰、抑制抖振,具有很强的鲁棒性。

Research on Sliding Mode Fuzzy Adapive Control in Electromotive power loading for Actuator of D-bomb

Aimed at tracking accuracy of a certain electromotive power loading for actuator of D-bomb with uncertainties and external disturbance, a new sliding mode adaptive control scheme connected with sliding mode variable structure control and fuzzy adaptive control is designed. An adaptive parameter adjuster and fuzzy control rules are introduced into sliding mode control. The adaptive law is used to adjust parameter of the controller and the fuzzy control law was used to attenuate the chattering phenomenon. Simulation results show that the proposed scheme can not only improve the tracking precision of the electromotive power loading for actuator of D-bomb, but also reduce the chattering and external disturbance effectively, and has good robustness.
