Study on Adaptive Cruise Internal Model Control Strategy of Truck

In order to resolve the difficulties of the truck, adaptive cruise control (ACC) technology, including how to extract radar targets and how to improve the control performance of the complex system. This paper presents a two-input/two-output time-delay system, idealizes to a first-order time-delay form, and an internal model PID (IMPID) control strategy is proposed. The simulation analysis and validation of the control strategy are carried out by Trucksim. The simulation results show that the IMPID control strategy can successfully realize the main functions and realize decoupling, the dynamic performance is excellent, and response is positive.
