Mesoscopic digital control for Practical String Stability of vehicular platoons

In this paper, we propose a new piecewise constant feedback for string-stability of a platoon under sampled and quantized measurements. The design is based on a mesoscopic approach and is carried out over the sampled-data model associated to each vehicle. The proposed feedback ensures string-stability in the practical sense independently of the effect of sampling and quantization. Simulations show the effectiveness of the results.
