In order to achieve the application of discrete-time hidden Markov model (DTHMM) in modeling and controlling the networked control system (NCS) with the network-induced delays in the forward channel, a simulation platform was designed and implemented in this paper by using TrueTime 1.5, which is a Matlab/Simulink-based simulator. There were one network module and four kernel modules (sensor, controller,...
The main objective of this paper is to demonstrate the feasibility of Internet-based remote monitored control system for teaching. An open-loop unstable dual-parallel coupled inverted pendulum platform is constructed and uses to develop the NCSs with real-time application interface. Client-Server architecture is developed with the network communication for closed-loop control. And a novel grey prediction...
The issue of stability analysis for nonlinear MIMO networked control systems (NCSs) is researched, where its network transmission is connected with network-induced delay and packet dropout. The effect of network-induced delay to the stability of nonlinear networked control system s is considered. Asymptotical stability under a multiple-packet transmission policy is analyzed and the maximum allowable...
Network-induced delays in a networked control system (NCS) are stochastic continuous variables that depend on the current network state, which, as an abstract and hidden variable, can not be well defined but can be perceived by the observation of the packet-delay process. We model the network in an NCS as a hidden Markov chain and the network delay as stochastic variable whose probability density...
For the stability analysis of the networked control system (NCS) with random network-induced delays, which were considered to be governed by an underlying Markov chain with unknown probability distribution, the hidden Markov model (HMM) theory was proposed to model this kind of NCS as a jump linear system, wherein the output feedback controller was adopted. By using Baum-Welch algorithm, the parameters...
