摘要
基于局部能达性与局部能观性的分析给出2-D连续-离散系统状态空间模型的平衡实现,这一实现的第i个状态分量的重要性由系统的能达、能观阵的第i个对角元素所度量,去掉平衡实现系统弱能达、弱能观的部分,从而得到2-D连续-离散系统的模型降阶。所给示例表明,该方法具有良好的降阶效果。
The model reduction of 2-D continuous-discrete systems is studied. Based on the local reachability and local observability for this systems, the balanced realization and balanced model reduction procedure are given. The illustrative example shows that this reduction methods is of satisfactory reducing performance.
