Abstract

This brief addresses the problem of asynchronous reduced-order filtering for Markov jump systems. The communication between the reduced-order filters and the systems is transmitted through the network. On the one hand, quantization is considered to save network resources; on the other hand, due to the measurement may not be perfect, the system information is a hidden component (i.e., it possesses inaccessibility), therefore reduced-order filters are designed by using the hidden Markov model. Then, the random stability of the plant is guaranteed by a set of conditions derived according to Lyapunov theory. Subsequently, the gains of the designed filters are obtained through decoupling. Finally, the effectiveness of the proposed approach in this brief is confirmed by utilizing a pulse-width-modulation-driven boost converter.

马尔可夫跳变系统的异步降阶滤波及其在PWM电路中的应用

本文简要地讨论了马尔可夫跳变系统的异步降阶滤波问题。降阶滤波器与系统之间的通信通过网络传输。一方面，量化考虑节约网络资源；另一方面，由于测量可能不完美，系统信息是一个隐藏成分（即它具有不可访问性），因此使用隐马尔可夫模型设计了降阶滤波器。然后，根据李亚普诺夫理论推导出一组条件来保证系统的随机稳定性。然后，通过解耦得到所设计滤波器的增益。最后，本文提出的方法的有效性通过利用脉冲宽度调制驱动的升压转换器得到证实。
