This work deals with the control design and development of an automated car-following strategy that
further increases robustness to vehicle dynamics uncertainties. The control algorithm is applied on a
hierarchical architecture where high and low level control layers are designed for gap-control and desired
acceleration tracking, respectively. A fractional-order controller is proposed due to its flexible frequency
shape, fulfilling more demanding design requirements. The iso-damping loop property is sought, which
yields a desired closed-loop stability that results invariant despite changes on the controlled plant gain.
In addition, the graphical nature of the proposed design approach demonstrates its portability and
applicability to any type of vehicle dynamics without complex reconfiguration. The algorithm benefits
are validated in frequency and time domains, as well as through experiments on a real vehicle platform
performing adaptive cruise control. |
