Cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. During such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. Therefore, to design and dev...

controller design remains an elusive and challenging problem foruncertain nonlinear dynamics. interval type-2 fuzzy logic systems (it2fls) incomparison with type-1 fuzzy logic systems claim to effectively handle systemuncertainties especially in the presence of disturbances and noises, but lack aformal mechanism to guarantee performance. in contrast, adaptive sliding modecontrol (asmc) provides...

‘whistleblowing’ has come to increased prominence in many health systems as a means of identifying and addressing quality and safety issues. but whistleblowing – and the reactions to it – have many complex and ambiguous aspects that need to be considered as part of the broader (organisational) cultural dynamics of healthcare institutions.

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...

It is obvious that the success of a project-based organization is dependent on its projects. A variety of tools such as the project excellence model, project management maturity models, the earned value method, have been developed in this regard, but there are still delays in projects because the projects have dynamic nature with non-linear relationships and feedback processes during the projec...

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

The important and hazardous of the rescue mission in oceans and seas, autonomous vessels now are one of the most appropriate applications among others. Due to safety, reliability, and accessibility of smart, Autonomous and Cooperative vessels today has attracted much attention from the industry. Regard to the complication of the mono vessel for different objects, the multi- agent system was pro...

time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. the stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. it is well-known that the stabi...
