It　is　difficult　to　model　the　process　of　complex　multi-agent　behaviors　coevolution.　Aiming　at　this　problem,　this　paper　presents　the　structure　of　MAS　intelligent　control　system　for　behaviors　coevolution,　and　based　on　Petri　net　method,　the　Petri　net　model　for　behaviors　coevolution　process　is　constructed.　The　characteristics　of　the　model　are　analyzed,　and　the　simulation　verification　was　done.　This　model　can　adequately　describe　the　flow　structure,　dynamic　behavior　rules　and　agents　interaction　mechanism　of　the　behaviors　coevolution　process.
