The time-varying and incommutable character of the coefficient matrix ofperiodically time-varying linear systemsare the bottleneck of the design for high precision direct integration methods. 周期时变线性系统系数矩阵的时变性与不可交换性是其精细积分算法设计中的瓶颈。
This article is concerned with robust stability analysis of discrete-time systems and introduces a novel and powerful technique that we call noncausal linear periodically time-varying (LPTV) scaling. Based on the discrete-time lifting together with the conventional but general scaling approach, we are...
Discrete-time linear periodically time-varying (LPTV) systems, considered as a bridge between the well-studied linear time-invariant (LTI) model and the nonlinear time-varying problems in real world, have been receiving increasing attention in recent a few decades.In this research project, we try...

This paper deals with the general linear quadratic optimal control (LQOC) problem for periodically time varying (PTV) linear systems, i.e. the LQOC when the state equation is non homogenous and the quadratic functional criterion contains linear terms. A series of necessary and sufficient ...
The considered class of systems is described by ordinary differential equations with coefficients that vary periodically over time, making use of multisines both for excitations as well as for the time-varying system parameters. To solve the model equation, an efficient frequency domain simulator is ...
Periodicity frequently occurs in hard disk drives (HDDs) whose servo systems with periodic phenomena can be usually modeled as linear periodically time-varying (LPTV) systems. This paper discusses optimal $H_{infty}$ control synthesis for discrete-time LPTV systems via discrete Riccati equations. Fir...
Frequency response of linear time periodic systems A frequency response for linear time periodic (LTP) systems that exploits the one-to-one map induced by geometrically periodic signals is developed. This m... NM Wereley,SR Hall - IEEE Conference on Decision & Control...
We study two discrete-time, linear switching time-varying (LSTV) structures, each of which consists of a periodic switch connected to several linear time-invariant (LTI) systems. Such structures can be used to represent any linear periodically time-varying (LPTV) systems. We give basic ...
