Asynchronous Resilient Output Consensus of Switched Heterogeneous Linear Multivehicle Systems With Communication Delay
Dan Zhang, Zhenhua Xu, Gang Feng, Hongyi Li · IEEE/ASME Transactions on Mechatronics · 2019
The resilient output consensus problem for a network of switched heterogeneous linear vehicle systems with asynchronous switching, controller gain variation, unknown disturbance, and communication delay is investigated. Based on the topology decoupling technique, the investigated problem is transformed into two subproblems: one is a robust asynchronous static output feedback (SOF) control problem and the other is an asynchronous SOF problem. Based on the piecewise Lyapunov functional method and the average dwell time switching scheme, some new sufficient conditions are proposed for the solutions to those subproblems. Moreover, some novel linear-matrix-inequality-based conditions are developed to calculate the SOF controller gains. A network of six vehicles is finally presented to show the effectiveness of the proposed resilient consensus controller.
