Getting noncooperative agents to cooperate:nudging and dynamic interventions

Due to the strong interconnection between modern engineering systems and their users, performance of these systems heavily rely on the user behavior. Therefore, uncoordinated user behavior can deteriorate the overall performance and entail undesired outcomes. To address this problem, this thesis studies the problem of designing suitable interventions that provide coordination among noncooperative agents/players. We investigate the development of suitable interventions in several setups and propose mechanisms that achieve a desired outcome. The first part of the thesis focuses on altering the aggregative behavior of noncooperative price-taking agents towards a desired stationary or temporal behavior. We address this problem by introducing a nudge framework, where a system regulator modifies the behavior of the agents by providing a price prediction signal. In the second part of the thesis, we focus on designing intervention mechanisms that steer the actions of noncooperative players in network games to the social optimum. We investigate different cases based on the knowledge of the system regulator on the game as well as constraints on the actions and interventions. The third part of the thesis deals with the problem of Nash equilibrium seeking in aggregative games. We develop a distributed algorithm where the players communicate to their neighboring players. The robustness and privacy preserving properties of the algorithm are also analyzed

Distributed dynamics for aggregative games:Robustness and privacy guarantees

This paper considers the problem of Nash equilibrium (NE) seeking in aggregative games, where the cost function of each player depends on an aggregate of all players' actions. We present a distributed continuous-time algorithm such that the actions of the players converge to NE by communicating to each other through a connected network. As agents may deviate from their optimal strategies dictated by the NE seeking protocol, we investigate robustness of the proposed algorithm against time-varying disturbances. In particular, we provide rigorous robustness guarantees by proving input-to-state stability (ISS) and (Formula presented.) -stability properties of the NE seeking dynamics. A major concern in communicative schemes among strategic agents is that their private information may be revealed to other agents or to a curious third party who can eavesdrop the communications. Motivated by this, we investigate privacy properties of the algorithm and identify to what extent privacy is preserved when all communicated variables are compromised. Finally, we demonstrate practical applications of our theoretical findings on two case studies; namely, on an energy consumption game and a coordinated charging of electric vehicles

Development of time delay current control for lead acid battery 12 v DC by using arduino

Development of time delay current control for lead acid battery 12 V dc by using Arduino is the aim of this thesis. The development problem is necessary before applying control techniques to guarantee the execution of any task according to a desired input with minimum error. The main objective of this thesis is to design the time delay has on the performance of a current controlled for the buck-boost converter. The time delay controller is generally regarded as a nuisance to a control system. In addition, the performance of the Arduino and MATLAB as a signal processing device interface time is used. The feedback of open loop and closed loop time delay controller is also been analyzed. Based on results, the experiment of closed loop hardware gives better results than simulation in terms of output current. Through this study it is proved that the time delay controller is successfully designed to control current for lead acid battery

Technological Capability in Industry 4.0: A Literature Review for Small and Medium Manufactures Challenges

Technological capabilities work as a basis for one to adapt and compete with the rapid pace of Industry 4.0 as without it worried the industry would get left behind hence this paper intends to give the low-down on the issues encountered regarding the technological capabilities in small and medium manufacturing enterprise (SME) due to the rise of Fourth Industrial revolution in manufacturing industry. Methods used are by reviews the literature on technological capabilities in the manufacturing sector based on journal articles, online news and books that strictly related to the keywords and research area. The concerns encountered in this paper are regarding the components of technological capabilities, and the challenges of technological capabilities face by manufacturers SME in Malaysia. Although a lot of researches uncover only the ground of technological capabilities hence there is a need to hit the books on the research area. Both empirical and non-empirical must carry out to discover more issues related to technological capabilities, and the study only covers the small and medium manufacturing enterprises in Malaysia
