The problem of data packet dropout and transmission delays induced by communication channel in networked control systems (NCSs) is studied in this paper. We model the continuous-time NCSs with data packet dropout and transmission delays as ordinary linear systems with time-varying input delays. By using the Lyapunov–Razumikhin function techniques,(More)
This paper is concerned with the problem of robust peak-to-peak gain minimization by linear matrix inequality (LMI) approach. Instead of minimizing the robustly induced L ∞-norm, we minimize its upper bound. Results on the state-feedback controllers are obtained by this approach, and the controllers are at most the same order as the plant. One of the main(More)
Glial cell line-derived neurotrophic factor (GDNF) has neuroprotective effects on dopaminergic (DA) neurons both in vivo and in vitro. However, substantial evidence has shown that a long-term overexpression of GDNF gene is often associated with side effects. We previously improved tetracycline (Tet)-On lentivirus system carrying human GDNF (hGDNF) gene, and(More)
— The problem of persistent bounded disturbance rejection for linear impulsive systems with parametric uncertainty is considered by Lyapunov function and positively invariant set analysis method. A sufficient condition for robustly internal stability and L 1-performance of the impulsive systems is obtained in terms of linear matrix inequalities. Based on(More)
