十多年来，非线性鲁棒输出调节问题的可解性依赖于外系统是线性且中性稳定的假设。因此，现有理论所能容纳的唯一外源信号是有限多个阶跃函数和正弦函数的组合。在这篇文章中，我们将证明找到能够接纳由非线性外系统产生的外部信号的控制器是可能的。给出了一个以著名的van der Pol振子为外系统的例子来说明我们的方法。
For over a decade, the solvability of the nonlinear robust output regulation problem relies on the assumption that the exosystem is linear and neutrally stable. Thus, the only exogenous signal that can be accommodated by the existing theory is a combination of finitely many step functions and sinusoidal functions. In this paper, we will show that it is possible to find controllers that can admit exogenous signals produced by nonlinear exosystems. An example with the well known van der Pol oscillator as the exosystem is given to illustrate our approach.
