Discrete Feedback Systems 1.

Classical Control

Modeling longitudinal dynamics

The simplified model of the longitudinal dynamics of the vehicle is shown in Figure 2.10. The longitudinal movement of the vehicle is influenced by the traction force Fl as the control signal and disturbances Fd. Several longitudinal disturbances influence the movement of the vehicle. The rolling resistance is modelled by an empiric form Fr=Fzf0(1+κξ ˙2), where Fz is the vertical load of the wheel, f0 and κ are empirical parameters depending on tyre and road conditions and ξ ˙ is the velocity of the vehicle. The aerodynamic force is formulated as Faero=0.5CwρA0ξ ˙rel2, where Cw is the drag coefficient, ρ is the density of air, A0 is the reference area, ξ ˙rel is the velocity of vehicle relative to the air. The longitudinal component of the weighting force is Gx=mgsinθ, where m is the mass of the vehicle and θ is the angle of the slope. Then, the acceleration of the vehicle is the following

The aim of the book is to provide a well-rounded exposure to analysis, control and simulation of discrete-time systems. Theoretical techniques for studying discrete-time linear systems with particular emphasis on the properties and design of sampled data feedback control systems are introduced. This book is intended to be used as a textbook in our MSc and PhD courses. We have tried to balance the broadness and the depth of the material covered in the book. The interested reader is also sent to consult the publications of the references list.
