Stabilizability Theorems on Discrete-time Nonlinear Uncertain Systems
Zhaobo Liu, Chanying Li
This paper derives two stabilizability theorems for a basic class of discrete-time nonlinear systems with multiple unknown parameters. First, we claim that a discrete-time multi-pa…
Inverse Eigenvalue Problem For Mass-Spring-Inerter Systems
Zhaobo Liu, Qida Xie, Chanying Li
This paper has solved the inverse eigenvalue problem for "fixed-free" mass-chain systems with inerters. It is well known that for a spring-mass system wherein the adjacent masses a…
Identification of Disturbed Control Systems
Chanying Li
This paper studies the identification of nonlinearly parameterized control systems in given experiments. Several identifiability criteria are established and an implementable algor…
On Instability of LS-based Self-tuning Systems with Bounded Disturbances
Shuai Xu, Chanying Li
It is well known that discrete-time linear systems can be stabilized by a least-squares (LS) based self-tuning regulator (STR), as long as noises are absent. However, this note sho…
Is It Possible to Stabilize Disrete-time Parameterized Uncertain Systems Growing Exponentially Fast?
Zhaobo Liu, Chanying Li
This paper derives a somewhat surprising but interesting enough result on the stabilizability of discrete-time parameterized uncertain systems. Contrary to an intuition, it shows t…
Supplementary Material to: Passive Controller Realization of a Biquadratic Impedance with Double Poles and Zeros as a Seven-Element Series-Parallel Network for Effective Mechanical Control
Kai Wang, Michael Z. Q. Chen, Chanying Li +1
This report presents some supplementary material to the paper entitled "Passive controller realization of a biquadratic impedance with double poles and zeros as a seven-element Ser…
