| 摘 要： | 若线性系统可被某状态线性反馈全局渐近镇定 ,饱和介入反馈后 (具有反馈的 )系统稳定性或得以保持 ,或降为区域渐近稳定 .本文作者就这一问题给出简洁判据 ,且对后者计算其不变吸引 (超 )椭球 ;在此基础上用叠代法求取使椭球尽量大的反馈增益 ;最后用算例说明方法的有效性 .

| Abstract: | Suppose a linear system can be globally asymptotically stabilized by a linear state feedback. As saturation intervenes into the feedback, the stability of the system is either to be kept, or degraded into regionally asymptotically stability. This paper presents a simple and clear method for calculating the invariant attractive ellipsoid in the latter case. An iterative algorithm is employed to solve a much better feedback gain so that the invariant attractive ellipsoid is as large as possible. At last, the validity of the approach is demonstrated by examples. |
