Optimal Sampled-Data Control Systems
Tongwen Chen,Bruce A. Francis +1 more
TL;DR: This paper proposes a direct attack in the continuous-time domain, where sampled-data systems are time-varying.
Journal ArticleDOI
A new delay system approach to network-based control
TL;DR: A sampled-data networked control system with simultaneous consideration of network induced delays, data packet dropouts and measurement quantization is modeled as a nonlinear time-delay system with two successive delay components in the state and the problem of network-based H"~ control is solved accordingly.
Journal ArticleDOI
A new method for stabilization of networked control systems with random delays
TL;DR: This work considers the stabilization problem for a kind of networked control systems in discrete-time domain with random delays, and it is shown that the state-feedback gains are different with different modes.
Journal ArticleDOI
New Results on Stability of Discrete-Time Systems With Time-Varying State Delay
Huijun Gao,Tongwen Chen +1 more
TL;DR: Several new conditions are obtained for the asymptotic stability of discrete-time systems with time-varying state delay by defining new Lyapunov functions and by making use of novel techniques to achieve delay dependence.
Journal ArticleDOI
${\cal H}_{\infty}$ Estimation for Uncertain Systems With Limited Communication Capacity
Huijun Gao,Tongwen Chen +1 more
TL;DR: This paper proposes a parameter-dependent filter design procedure, which is much less conservative than the quadratic approach and provides alternatives for designing robust Hinfin filters with different degrees of conservativeness and computational complexity.
