This paper generalizes the pole placement method to the case of improper transfer. In that case, the minimal order solution may be non unique. After some illustrating examples, the problem of active control of a vehicle drivetrain is investigated. The control design is based on a simplified model including a non proper approximation of the delay. A methodic choice of the closed loop poles leads to...
This paper deals with a hierarchical architecture of the Engine Control Unit (ECU) made-up of two levels: the higher one, called powertrain level, computes the current and the future torque demands; The lower level, called engine level, uses these information to provide an appropriate motor control. In continuous-time framework, a H2-control design with preview is proposed for the lower level and...
In this paper an original modeling approach is proposed. This approach is based on power exchanges and highlights the most influential parameters of a complex system, without having to choose particular technological solutions. This is thus a particularly well suited solution for a first and global design or for the validation of a concept. This approach has been efficiently used for the optimal sizing...
