Active suspension design for a tractor by optimal control methods.
Report, Bibliographie
Kurzbeschreibung (Abstract)
An active suspension system for improving the ride comfort and safety of a tractor is investigated. The underlying planar dynamic tractor model and a suitable objective for optimal suspension are introduced. The problem of optimal active suspension leads to a linear-quadratic optimal control problem. Classical Linear-Quadratic Regulator (LQR) theory provides a closed-loop control for the steady state problem which is optimal only for an initial disturbance input from the road. A direct transcription method can handle more general disturbances and models but provides only an open-loop solution, where the time history of the optimal control is given along the optimal trajectory for one type of deterministic disturbance and initial value only. Simulation results for two different road disturbances are given comparing both approaches.
