在分析冲击振动控制特性以及已有控制算法的缺陷基础上,提出了一种新的冲击振动自适应逆控制方法,该方法可以根据负载特性的不同自适应地调整逆控制器参数,提高系统控制精度及鲁棒性,完全解决了传统频域控制方法中低频分辨率低、易产生溢出的问题.同时,为了减少算法计算复杂度及缩短算法的收敛时间,提出了一种快速X滤波LMS算法,运用批处理技术,使运算效率得到提高.最后对算法进行了实验验证,结果表明文中提出的控制方法精度较高、算法计算量小,明显优于已有的控制方法.

Through analyzing the characteristic of shock vibration control and the limitation of former algorithm, a method of shock vibration control based on adaptive inverse control is raised to improve the accuracy and robust of the system. It can adjust the parameter of the controller according to the different load and can solve the problems of low resolution at low frequencies and overflow. In order to decrease the computation complexity and shorten the convergence time of the filter-X LMS algorithm, a fast block filter-X LMS algorithm is put forward. The practical result shows the algorithm performance is better than former algorithm.
