- Optimal switching of switched systems with time delay in discrete time
- AUTOMATICAXu, Wei Feng, Zhi Guo Lin, Gui-Hua Yiu, Ka Fai Cedric Yu, Liying 出版年：2020
- This paper addresses a kind of optimal switching problem to minimize a quadratic cost functional for the discrete-time switched linear system with time delay. Since the dynamics is influenced by the switching sequence an...
- Finite-time stabilization for a class of nonlinear systems via optimal control
- MATHEMATICS AND COMPUTERS IN SIMULATIONZhang, Yu Feng, Zhi Guo Yang, Xinsong Alsaadi, Fuad E. Ahmad, Bashir 出版年：2018
- In general, finite-time stabilization techniques can always stabilize a system if control cost is not considered. Considering the fact that control cost is a very important factor in control area, we investigate finite-t...
- Design of Sparse Filters by a Discrete Filled Function Technique
- CIRCUITS SYSTEMS AND SIGNAL PROCESSINGFeng, Zhi Guo Yiu, Ka Fai Cedric Wu, Soon Yi 出版年：2018
- In this paper, we consider the sparse filter design problem where some of the coefficients can be reduced to zeroes in order to lower implementation complexity. The objective is to choose the fewest number of nonzero fil...
- Optimal Design of IIR Filters via the Partial Fraction Decomposition Method
- IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS II-EXPRESS BRIEFSQi, He Feng, Zhi Guo Yiu, Ka Fai Cedric Nordholm, Sven 出版年：2019
- In this brief, we consider the minimax design of infinite impulse response (IIR) filter. First, we apply the partial fraction method to decompose the transfer function into a sum of low order fractions, as a result the m...
