Dynamic Programming and Time-Varying Delay Systems
… of stability and performance of systems with time-varying delays. The two papers presented in the first part attacks optimal control problems with finite but rapidly increasing search space. In the first paper we try it reduce the complexity of the optimization by exploiting the structure of a …

Communication protocols, queuing and scheduling delay analysis in CANDU SCWR hydrogen co-generation model
… a communication network. We study a continuous-time CANada Deuterium Uranium-Super Critical Water Reactor (CANDU-SCWR) hydrogen plant and a discrete-time controller, sensor and actuator block, that are connected via a communication network, such as e.g. controller area network (CAN), Ethernet or …

Strategies for wireless networked control systems
… network. The inclusion of the network introduces delays and dropouts, which greatly influence the stability and robustness of the controller. While there is wealth in theoretical contributions to NCS, it is still imperative to study more applications and investigate the effects of networks in a …

Data analytics for stochastic control and prognostics in cyber-physical systems
… A PDF identifier is proposed to capture the time-varying delays and its distribution. With the modification of traditional stochastic optimal control using PDF of delays, the assumption of full knowledge of network imperfection in priori is relaxed. This proposed controller is considered a …

Robust Control of Input-Delay Linear Parameter-Varying (LPV) Systems
Practical systems are nonlinear and time-varying and thus linear techniques can expose their control design to extra conservatism. Nevertheless, the Linear Parameter-Varying (LPV) representation can effectively describe them, which in contrast to linearization, maintains the principal dynamic modes …

Formation control of multiple robots under packet loss
… includes challenging conditions, such as time-varying delays, which initially caused oscillations in the system. By applying an input-shaping filter, the oscillatory behavior is mitigated, and the stability of the system is restored. The LSTM-based linear control strategy exhibits …

Consensus in multi-agent systems with time-delays
… and stability analysis of consensus problems, time-delay systems, and sampled-data systems have been presented. Novel contributions have been illustrated in Chapters 5-8. Particularly, in Chapter 5 we reported the results of Zareh et al. (2013b), where we investigated the consensus problem for …
