Sliding mode control design based on Ackermann's formula. Jürgen Ackermann, Vadim I. Utkin. Sliding mode control design based on Ackermann's formula. IEEE Trans. Automat. Contr., 43(2): 234-237, 1998.2006-01-3638. Ackermann steering geometry relates the steer angle of an inside tire to that of the outside tire. When turning the inside tire travels a shorter radius than the outside tire and thus must have a greater steer angle to avoid tire scrub. Classic Ackermann minimizes scrub by positioning both tires perpendicular to the turn center.
