Cooperative control of multi-agent systems has been extensively studied in recent literature due to its large number of applications. We focus on cooperative control design for nonlinear multi-agent systems. Our control objective is to ensure that a group of agents reaches a formation characterized by external time-varying parameters. Based on previous results dealing with circular motions, the main idea is to transform the circular trajectories of a stable autonomous exosystem and to enforce the multi-agent system to track these transformed trajectories. Firstly, a translation control design is presented to stabilize the multi-agent system to a circular motion tracking a time-varying center. Then, we propose a new framework based on affine transformations to extend previous results to more complex time-varying formations. Moreover, both control laws are improved adding a cooperative term to distribute the agents uniformly along the formation. In addition, we present two applications of this approach: heterogeneous multi-agent systems consensus and formation control for distributed source-seeking.
