Partial component consensus refers to the phenomenon that some components of all state variables of multi-agent systems become asymptotically identical, so it is a dynamic behavior that is weaker than identical consensus. Based on a dynamical model of second-order multi-agent systems, this paper designs an adaptive intermittent pinning control protocol, converts the state components to be studied in the original error system into the state components of the previous part of the new error system through the permutation matrix method, and uses the matrix theory and partial variable stability theory to derive out the partial component consensus criterion, so as to ensure the consensus according to exponential trend. Finally, the numerical simulation verifies the theoretical analysis.
