in this paper, the optimal adaptive leader-follower consensus of linear continuous time multi-agent systems is considered. the error dynamics of each player depends on its neighbors’ information. detailed analysis of online optimal leader-follower consensus under known and unknown dynamics is presented. the introduced reinforcement learning-based algorithms learn online the approximate solution...

in this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. it provides both robust tracking and load swing suppression. inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. the crane nonlinearities are then tr...

Resilience is challenging for small- and medium-sized enterprises (SMEs), as their structure hinders them from overcoming external disturbances. This article used control to model how these perspectives can lead SMEs equilibrium. We adopted a systemic approach, which addresses organizational complexity via linear modeling. First, using social network analysis (SNA), we revised the understanding...

Abstract Prior to landing of reusable space transportation systems, the vehicle’s legs needs be fully deployed enable a safe and further re-use vehicle. During that phase deployment system has overcome harsh challenging environmental conditions. In this study, numerical simulator is developed in order investigate these influences on leg dynamics. By means an extensive aerodynamic database broad...

Increasingly, firms are outsourcing their processes. Outsourcing regards not only peripheral activities but portions of key activities as well. Outsourcing is a pervasive phenomenon that often overlaps, and interferes with, the strategic decision to define a firm’s boundaries. By outsourcing phases of R&D processes, for example, firms may lose their know-how concerning the production of core pr...

in this study, eutrophication was investigated in lake ontario to identify the interactions among effective drivers. the complexity of such phenomenon was modeled using a system dynamics approach based on a consideration of constant and variable stoichiometric ratios. the system dynamics approach is a powerful tool for developing object-oriented models to simulate complex phenomena that involve...
