Output consensus seeking of mixed-order multi-agent systems

Output consensus problem is investigated for the mixed-order multi-agent system, which is composed of two types agents with one and two poles at the origin respectively. According to generalized Nyquist stability criterion, consensus conditions are gained for the mixed-order multi-agent systems to achieve an asymptotic stationary consensus. Besides, output consensus is also analyzed for a simplest mixed-order multiagent system, which is composed of single and double integrators. Numerical examples demonstrate the correctness of the results.
