Differential driven unmanned ground vehicles (UGVs) and quadrotor unmanned aerial vehicles (UAVs) are linearized as first-order integrators and fourth-order integrators respectively in this paper. Consensus problem is investigated for a heterogeneous multi-agent system composed of first-order and fourth-order agents. Firstly, consensus convergence for heterogeneous multi-agent systems is studied with...
Focusing on the time-delay problem of multi-agent systems, this paper provides solutions for flocking of systems with time-delay. For the circumstance with a virtual leader, the agents would follow the virtual leader and achieve the same velocity asymptotically. Systems with homogeneous and inhomogeneous time-delays are discussed respectively. The appropriate simulation circumstance is set up, and...
Variable universe adaptive fuzzy controller tunes automatically the contraction-expansion factor and universe varies with error of the system. By this approach, the accuracy and the adaptivity of the system can be improved. Aiming at the nonlinearity and time-delay of the plant, a variable universe adaptive fuzzy control for liquid lever system is proposed. First, the mathematical model of the plant...
