Prediction Based Cooperative Adaptive Cruise Control for Heterogeneous Platoons with Delays

We present a prediction based controller for heterogeneous platoons with actuation delay. By using a prediction of the ego vehicle’s acceleration and compensating the ego vehicle’s influence on the error dynamics, we obtain a controller that achieves input-to-state stability (ISS) with respect to the preceding vehicle’s acceleration. The result is a controller that does not require driveline information of the preceding vehicle, which enables platooning in a heterogeneous setting. An analysis is presented of the string stability properties of the system with both actuation and communication delays. The effectiveness of the controller is shown in simulation.
