Network Protocols for Networked Control Systems

Input-Output Stability of Networked Control Systems With Stochastic Protocols and Channels

This paper introduces a new definition of stochastic protocols for networked control systems (NCS) and the stochastic analogue of the notion of uniform persistency of excitation of protocols first presented in [1]. Our framework applies directly to common wireless and wireline NCS, including those built on collision-sense multiple access (CSMA) style protocols, with Ethernet and 802.11a/b/g as ...

Stochastic Distribution Control Strategy with Application to Networked Control Systems

In this paper, the minimum error entropy criterion has been utilized to design controller for non-linear networked control systems (NCSs), where time delays in the communication channels are of random nature. A recursive optimization solution has been developed based on the recently developed stochastic distribution control strategy. The local stability condition of the closed loop NCSs has bee...

Stochastic Delay Estimation and Adaptive Control of Networked Control Systems

An adaptive algorithm is introduced in this paper to estimate random communication time delay in Networked Control Systems (NCS). The algorithm updates an adaptive delay estimate using gradient descent method, and identifies plant parameters by a modified RLS. By using this algorithm, future control sequences are generated to compensate for the communication time delay when control signals are ...

A Model Predictive Control Approach for Stochastic Networked Control Systems

In this paper we present a stochastic model predictive control (SMPC) approach for networked control systems (NCSs) that are subject to time-varying sampling intervals and timevarying transmission delays. These network-induced uncertain parameters are assumed to be described by random processes, having a bounded support and an arbitrary continuous probability density function. Assuming that the...
