摘  要:针对由摩擦等非线性因素导致防空火箭炮随动系统控制精度降低的问题,提出一种基于乌鸦搜索改进超螺旋滑模控制方法。传统滑模控制器由于切换控制律中不连续符号函数的存在产生了较大抖振,通过设计超螺旋滑模控制方法将原有滑模控制律中符号函数改为连续函数,减少系统抖振,并设计乌鸦搜索算法优化超螺旋滑模控制器中切换增益,提高系统的控制精度和鲁棒性。仿真结果表明:基于乌鸦搜索改进超螺旋滑模控制器较传统滑模控制器减小了系统抖振,提高了系统位置跟踪精度,缩短了响应时间,对负载干扰具有较强的抑制能力。Aiming at the issue of reduced control accuracy of air defense rocket artillery servo systems caused by nonlinear factors such as friction,an improved super-twisting sliding mode control method based on the crow search algorithm is proposed.The traditional sliding mode controller has great chattering due to the existence of a discontinuous sign function in the switching control law.The super-twisting sliding mode control method is designed to replace the sign function in the original sliding mode control law with a continuous function to reduce system chattering.Additionally,the crow search algorithm is designed to optimize the switching gain in the super-twisting sliding mode controller and enhance control accuracy and robustness of the system.The simulation results show that,compared with the traditional sliding mode controller,the super-twisting sliding mode controller based on crow search optimization reduces system chattering,improves system position tracking accuracy,shortens response time,and has a robust ability to suppress load interference.
