Distributed coordinated tracking for the Lagrange network systems via quantized data exchange

This note investigates distributed coordinated tracking for the Lagrange network systems under quantized data exchange. A logarithmic quantizer is designed. Based on the quantizer, the tracking problem is studied by means of the differential inclusion theory. A criterion for the tracking with error bound is rigorously proven. A numerical example for the unmanned underwater vehicles (UUVs) verifies the new results.
