Securing of the communication is the key parameter for all wireless networks. WLAN's vulnerability to security threads is solved by several security mechanisms but all of these mechanisms have negative impact to the communication speed and final network performance. Time consumption of different security mechanisms used in wireless networks limits availability for several time-sensitive applications...
In order to effectively restrain the impact of network delays which are brought because of bandwidth constraint, path loss, signal attenuation and ambient noise in wireless networked control systems (WNCS), aiming at time-variant network delays and imprecise Smith predictor models, a new approach is proposed that novel Smith dynamic predictor combined with back propagation neural network (BPNN) control...
In order to overcome poor adaptability of conventional PID controller and effectively restrain the impact of network delays, a novel approach is proposed that new Smith predictor combined with neuron adaptive control for the wireless networked control systems (WNCS). Because new Smith predictor doesnpsilat include network delay model, therefore network delay is no need to be measured, identified or...
In this paper, a novel approach is proposed to deal with network delay, based on new Smith predictor combined with generalized predictive control (GPC) for wireless networked control systems (WNCS). Because new Smith dynamic predictor hides predictor model of the network delay into real data transmission process, further the network delay no longer need to be measured, identified or estimated on-line...
This paper aims at time-variant or uncertain wireless network delay in the wireless networked control systems (WNCS), a new Smith dynamic predictor is proposed.Because new Smith dynamic predictor hides predictor model of the network delay into real transmission process of the network data, further the network delay no longer need to be measured, identified or estimated on-line. It is applicable twosome...
Wireless network delay is the main factor that deteriorates the performance of the wireless networked control systems (WNCS). In order to effectively restrain the impact of network delay, as well as controlled plant might be time-variant or nonlinear, a novel approach is proposed that new Smith predictor combined with fuzzy radial basis function neural network (FRBFNN) for the WNCS. Because new Smith...
This paper aims to the time-variant, random and uncertain wireless network delay, a novel approach is proposed that new Smith predictor combined with the CMAC-PID control for the wireless networked control systems (WNCS). This new Smith predictor does not include the prediction models of the network delays, therefore network delays are no need to be measured, identified or estimated on line. It is...
Wired and wireless network delays highly degrade the control performance of hybrid networked control systems(HNCS). In order to effectively restrain impact of network delay for the HNCS, a novel approach is proposed that new Smith predictor combined with fuzzy radial basis function neural network (FRBFNN), and comes true delay compensations. Because new Smith predictor does not include network delay...
