利用Popov-Lyapunov方法研究了扰动Lure系统的稳定性。多变量Popov判据用于保证标称系统的稳定性，然后通过使用为标称系统开发的李雅普诺夫函数来研究扰动系统的稳定性。一个鲁棒性的措施，给出了一些允许的扰动系统的界限推导，避免使用范数形式。拟议措施的一个特点是，观察个别参数偏差的范围是可行的。>
The stability of a perturbed Lure system is studied through the Popov-Lyapunov approach. The multivariable Popov criterion is used to guarantee the stability of the nominal system, and then the stability of the perturbed system is investigated by using the Lyapunov function developed for the nominal system. A robustness measure which gives some bounds on allowable perturbations for the system is derived, evading the use of norm forms. A feature of the proposed measure is that the observation of the range for individual parameter deviation is feasible. >
