Abstract: Control of automotive vehicles and engines is a relatively new field in automatic control. Some current applications for engine control are described. Future nonlinear and time-varying automotive systems will require the development of more advanced control schemes. Representative examples for plant modeling, parameter and state estimation, and adaptive control are presented. Therefore, in this thesis the approach of using such additional communicated information from either the second predecessor or the platoon leader is combined with the use of PLC as control method. The goal is to investigate whether any of these two configurations give an increase in performance compared with similar configurations with PLC as control method and compared with a more basic configuration that uses just the direct predecessor’s state information with either PLC. Also, the possibly added value of using communicated predicted states, in addition to current states, with PLC is investigated. The CRUISE CONTROL controllers are designed to control the throttle, the brakes, and the gears, subject to operational constraints on acceleration, velocity, and vehicle-to-vehicle distance. The PLC- based CRUISE CONTROL controller contains a proportional feedback of the errors in velocity, position, and acceleration, combined with an automatic transmission scheme, and the control input is restricted at time instants at which a constraint is (almost) violated. The PLC-based CRUISE CONTROL controller at each time step minimizes the expected errors in position and velocity and the corresponding input variation.
