Aperiodically intermittent saturation consensus on multi-agent systems with discontinuous dynamics

This paper mainly investigates the exponential consensus problem for the multi-agent systems (MASs) with nonlinear discontinuous dynamics and time-varying delay. A novel aperiodically intermittent distributed control strategy is proposed to force the state of each agent to the common trajectory, where the configuration of control width and rest width can be aperiodic. Meanwhile, in order to limit the control effects into certain reasonable ranges, an improved saturation algorithm is proposed, which effectively reduces the non-smoothness of the control signal. Sufficient conditions for the exponential consensus on the discontinuous MASs are obtained through the Filippov differential inclusion (FDI), the Lie derivative method (LDM) and the measurement selection theorem (MST). Finally, the validity and feasibility of the main theories is demonstrated by numerical simulations.(c) 2022 ISA. Published by Elsevier Ltd. All rights reserved.

Automated summary

This paper investigates the exponential consensus problem for multi-agent systems with nonlinear discontinuous dynamics and time-varying delay. A novel aperiodically intermittent distributed control strategy is proposed to force the state of each agent to a common trajectory. An improved saturation algorithm is also proposed to limit the control effects within reasonable ranges. Sufficient conditions for exponential consensus are obtained through the use of Filippov differential inclusion, Lie derivative method, and measurement selection theorem. Numerical simulations are conducted to demonstrate the validity and feasibility of the proposed theories.
