Abstract: |
A continuous-time distributed optimization was researched for second-order heterogeneous multi-agent systems. The aim of this study is to keep the velocities of all agents the same and make the velocities converge to the optimal value to minimize the sum of local cost functions. First, an effective distributed controller which only uses local information was designed. Then, the stability and optimization of the systems were verified. Finally, a simulation case was used to illustrate the analytical results. |
Key words: distributed optimization heterogeneous multi-agent system local cost function consensus |
