Tracking Control for Sampled-data Systems with Uncertain Time-varying Sampling Intervals and Delays

In this paper, a solution to the approximate tracking problem of sampled-data systems with uncertain, time-varying sampling intervals and delays is presented. Such time-varying sampling intervals and delays can typically occur in the field of Networked Control Systems (NCS). The uncertain, time-varying sampling and network delays cause inexact feedforward, which induces a perturbation on the tr...

Performance of CCC-r control chart with variable sampling intervals

The CCC-r chart is developed based on cumulative count of a conforming (CCC) control chart that considers the cumulative number of items inspected until observing r nonconforming ones. Typically, the samples obtained from the process are analyzed through 100% inspection to exploit the CCC-r chart. However, considering the inspection cost and time would limit its implementation. In this paper, w...

Indirect sampled-data control with sampling period adaptation

It is known that if a continuous-time feedback system is exponentially stable, then the corresponding sampled-data system obtained by sample-hold discretization with constant sampling period is also exponentially stable, provided that the sampling period τ > 0 is sufficiently small. In general it is difficult to estimate how small the sampling period has to be in order to achieve stability of t...

H∞ Sampled-Data Controller Design for Stochastic Genetic Regulatory Networks

Artificially regulating gene expression is an important step in developing new treatment for system-level disease such as cancer. In this paper, we propose a method to regulate gene expression based on sampled-data measurements of gene products concentrations. Inherent noisy behaviour of Gene regulatory networks are modeled with stochastic nonlinear differential equation. To synthesize feed...
