在本文中，作者提出了新的李雅普诺夫和拉格朗日稳定性的临界情况下的脉宽调制（PWM）反馈系统的类型2调制。这里考虑的线性设备被假定为临界稳定的，即，该设备在原点处具有且仅具有一个极点，其余极点在复平面的左半部分中。一个算法被纳入，以方便计算的稳定性界限。通过两个具体的例子证明了本结果的适用性。
In this paper, the author presents new Lyapunov and Lagrange stability results for the critical case of pulse-width-modulated (PWM) feedback systems with type 2 modulation. The linear plant considered herein is assumed to be critically stable, i.e., the plant has one and only one pole at the origin and the rest of the poles are in the left half of the complex plane. An algorithm is incorporated to allow easy calculation of the stability bound. The applicability of the present results is demonstrated by means of two specific examples.
