主要学术成果:
纪志坚教授对群体智能系统和切换系统的三大基本问题，即能控性、镇定性和一致性开展了系统深入地研究，主要成果包括:
1. 首次给出了群体智能系统在信息交换图拓扑结构、分布式协议设计和领航者选取这三方面针对能控性和镇定性的统一理解；首次以定量方式揭示了群体系统能控性图理论特征刻画的复杂性成因，归纳提出了获得图理论特征刻画的一般步骤。
2. 突破性地建立了线性切换系统能控实现的切换序列理论，不仅给出了切换系统关于能控的代数和几何判据之间的关系，还第一次通过能控子空间迭代给出了能控实现所需切换序列的构造方法，进而揭示了切换次数与能控子空间维数的关系，并给出了迄今为止能控实现所需的最少切换次数。
3. 得到了一批实现一致性和包围控制的充分和/或必要条件，所获成果揭示了经典稳定性理论在多智能体网络系统研究中的重要应用，成果涉及一致性的快速收敛、二分一致、时变时滞、有向拓扑、切换拓扑和系统的非线性动态等。
