Engineering a decentralized system of autonomous service components and ensembles having multiple and interacting feedback loops is very challenging. While several works have expressed feedback loops as first-class entities, very little attention has been given to providing actual tool support. In this paper, we propose a novel approach to architect and engineer self-adaptive systems based on feedback loops. We also present the first implementation of SimSOTA, an Eclipse plug-in being developed to support the modeling, simulating and validating of self-adaptive systems based on our feedback loop-based approach. We validate our approach using a case study in cooperative electric vehicles.
