摘要: 研究一般的非线性多输入多输出系统状态观测器的设计问题,采用状态非线性变换讨论了这种观测器的设计方法及条件。将这种设计方法应用于某聚合反应釜的状态观测,表明这种观测器具有良好的收敛性,在参数变化10%时仍具有一定的鲁棒性。Abstract: The observer design problem for general nonlinear multi-input and multi-output system by nonlinear state transformation is studied. The observer design conditions and method are generalized. This design method is applied to the state observer of a polymenzation reactor. The results show that the observer has good convergence and robustness.
