利用极值思想与数值计算技术推广了谢聂稳定性判据 ,为系统的鲁棒稳定性判别与鲁棒镇定提供一个简便实用的方法 .同时指出将极值思想与数值计算技术相结合来解决当前的系统鲁棒性问题 ,能有效克服单纯采用传统数学工具确定鲁棒问题所导致的数学危机
The method of extreme value and numerical calculation is used to extend the Xie Nie stability criterion and provide a simple and practical method for the system robust stability discrimination and robust stabilization. Meanwhile, it is pointed out that the extreme value theory and the numerical calculation technique are combined to solve The current system robustness problem can effectively overcome the mathematical crisis caused by simply using traditional mathematical tools to identify robust problems
