研究一类切换动力系统的鲁棒控制问题。开关由脉宽调制（PWM）控制。例如，这种想法被用于电力电子设备中的电力转换。所考虑的系统类别包括许多不同类型的数字控制功率转换器。传统的功率转换器控制设计方法依赖于平均模型，该平均模型忽略了高频行为和由于采样而导致的固有时间延迟。相比之下，这里提出的方法是基于采样数据模型，其中考虑到系统的切换性质。采样数据模型近似为线性二次模型，采样数据H∞理论可以扩展到该模型。该方法被应用到一个双向升压变换器，这是受到一个大的负载扰动。
Robust control of a class of switched dynamical systems is considered. The switching is controlled by pulse-width modulation (PWM). This idea is used, for example, in power electronics for power conversion. The class of systems considered includes digitally controlled power converters of many different types. The traditional approach to control design for power converters rely on an averaged model that ignores the high frequency behavior and the inherent time delay due to sampling. In contrast, the method presented here is based on a sampled-data model which takes the switched nature of the system into account. The sampled-data model is approximated by a linear quadratic model to which sampled-data H∞theory can be extended. The approach is applied to a bidirectional boost converter which is subjected to a large load disturbance.
