【摘要】 为了提高单轴伺服系统的抗扰动能力和动态响应性能,基于现代控制算法设计了终端滑模-自适应模糊跟踪控制器。由于交叉耦合控制(CCC)结构可以实现轴间信息共享,故采用此结构提高镜像运动的两轴间的同步精度。利用Matlab/Simulink仿真平台,模拟了持续扰动作用下两轴跟踪正弦信号的同步运行过程,通过对比于传统PID控制器的响应曲线,证明了所提出的控制方法能够提高伺服轴的信号跟踪能力,更好地抑制扰动并减小同步误差。更多还原

【Abstract】 In order to improve the anti-disturbance ability and dynamic response of single-axis servo system,a terminal sliding adaptive fuzzy tracking controller is designed based on modern control algorithm.Because the cross-coupling control( CCC) structure can realize the information sharing between the axes,the synchronization accuracy between the two axes of the mirror motion can be improved by using this structure. Using M atlab/Simulink simulation platform,the synchronous operation process of two-axis tracking sinusoidal signal under continuous disturbance is performed. The response curve of the proposed control method is compared with that of the traditional PID controller. It is proved that the proposed control method can improve the signal tracking ability of the servo shaft,suppress the disturbance better,and reduce the synchronization error.更多还原
