Autocruise Control of a Heavy-Duty Truck with Robust Performance 942329

Robust performance control of an autocruise system for a heavy-duty truck is described. The controller design is carried out employing a loopshaping method, considering dynamics variation caused by the gear shift, the load changes, the vehicle speed and also the vibrational characteristics of the propulsion system as the plant uncertainty. Thereby a robust-stable controller is obtained without sacrificing the response to disturbances. Finally, nonlinear simulations and real vehicle experiments prove that the steady-state performance and its robustness excel the conventional PID's.
