摘要
针对具有参数摄动和外在干扰的某位置跟踪伺服系统,提出了一种基于特殊区域特征向量配置的滑模变结构控制策略。为了使系统实现快速到达和削弱抖振,控制函数采用指数趋近律。仿真结果表明新的滑模控制算法缩短了调节时间,并且减小了超调,使系统具有更强的鲁棒性.
For the position tracking serve system which has a parameter perturbation and external disturbance,a new design approach of the sliding-mode variable structure controller based on the specific eigenvector of the specific area is presented.In order to accelerate the reaching phase and reduce chattering,the exponential approach law is adopted as the control function.Simulation results show that the new control algorithm exhibits the better control performance than the classical control method.Moreover,its realization is simple and convenient.
