Difference between multi-agent systems and distributed systems
What is the difference between multi-agent systems (MAS) and distributed systems, in the context of control with agents?

Multi Agent System
According to the book;  Innovations,theories in  multi agent systems and applications, September,2015 

It states that in multi agent system,agents have the ability to solve complex real world problems besides being autonomous and interlinked. thus exhibiting some intelligence

Therefore,MAS falls under the umbrella of Distributed Artificial intelligence.e.g. Autonomous cars,SoftBots to mention but a few.

On the otherhand in Distributed systems,agents perform a specific task with the centralised agent taking control of the goal,that's achieved.e.g cellular network applications controlled by NOC,aircraft system that is controlled by Area Control Centres.

Therefore,Distributed systems,fall under the umbrella of  Distributed Computing
