This paper deals with of stabilization problem of a class of networked control systems over an additive white Gaussian noise (AWGN) channel. The signal-to-noise ratio (SNR) required for stabilisability is first transformed into L2–L∞ performance so that a linear matrix inequality (LMI) approach can be used. Then a network-induced delays model is proposed, which is more realistic as it can incorporate...
This paper discusses the technical structure and utilization of remote supervisory control system. And the novel dual-parallel coupled inverted pendulum platform is constructed. Client-Server architecture is developed with the network communication for closed-loop control. The application allows performing a number of laboratory scale hard real-time control experiments, which can be remotely monitored...
This paper presents a grey predictive control method for a class of nonlinear systems with unknown input delay. By using BP neural network, the unknown input delay is identified firstly. The system output is then estimated by the grey predictive algorithm. The output feedback control is fulfilled by PID algorithm which is used to tune its three parameters. By means of combining grey predictive algorithm...
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...
This paper investigates the stabilization of nonlinear networked control systems (NCSs) subject to two types of uncertainties. Firstly, the nonlinear NCS is modeled as a continuous-time Takagi-Sugeno (T-S) fuzzy system, and network-induced delays are represented using fuzzy rules which are designed by the parallel distributed compensation (PDC) technique. Then the norm-bounded uncertainty existing...
In this paper the performance improvement of wireless networks caused by chirp spread spectrum (CSS) as PHY is addressed. Firstly, the bit error rate function is firstly derived theoretically. Then an OPNET modulation curve is created through EMA (external model access) programming using the BER result. By doing this, CSS is introduced into OPNET as an alternate modulation method. Furthermore, simulations...
Networked control has attracted significant amount of interests from both the industry and academic in recent years due to flexible applications and many other advantages. Although various algorithms have been proposed for networked control systems (NCS), most control strategies assume that system model is known dasiaaprioripsila. Then one of the main tasks is to compensate the system dynamics due...
