报告内容简介:
Multi-agent cooperation involves a collection of decision-making components with limited processing, limited sensing and limited communications capabilities, all seeking to achieve a collective objective. Well known examples include mobile sensor networks for environment monitoring and surveillance and multi-UAV (unmanned aerial vehicle) formation flight.
In this talk, the leaderless and leader-following consensus problems are considered for a class of discrete time multi-agent systems with limited communication data rate. Under a connected undirected communication network, a quantized observer-based encoding-decoding scheme is designed and a distributed control law based on the outputs of the encoders and decoders is proposed. With the help of the perturbation analysis of matrices and quantization technique,
it is shown that n bits of information exchange between agents are enough to guarantee the quantized leaderless and leader following consensus with an exponential convergence rate, when
each agent is in the form of the n-th order integrator with one measurable state variable. Formation with 12 quadcopters which was presented at Singapore Airshow 2014 will be demonstrated.
