摘要
提出一种新型的扩张状态观测器。将作用于实际运行环境中的非线性系统的内外扰归结为“未知扰动”，利用输入输出数据对系统的状态变量及扩张的状态变量进行实时估计并补偿。仿真结果表明，这种新型的扩张状态观测器可以很好地消除系统的内外扰动影响，具有一定的实际应用价值。
A new type of extended state observer is introduced. Inner and external perturbations of nonlinear system that operated in actual environment were boiled down to ＂unknown perturbations＂. State variable and extended state variable of system were estimated and compensated by input and output data. Simulation result shows that this new type of extended state observer can eliminate the influence of system inner and external perturbations, and it has actual application value.
