This methodology makes the results in the present paper of general interest for all those applications in which a control system must be designed and tuned while dealing with the dispersion coming from production spreads and tolerances which make the underlying plant (i.e., the final vehicle) different from that used for design purposes. The resulting research area requires tools both of control theory and optimization, combined with the specific application-domain knowledge.
The presented results are based on a joint research work between the Politecnico di Milano and the R&D Department of the SAME Deutz-Fahr Group (SAME, Lamborghini, Deutz-Fahr, Hürlimann, Adim Diesel and Deutz AG). The work has been focused on a power-shift transmission designed for high-power (200 HP) agricultural tractors (see Fig. 1).
