Detailed Description

An (almost) linear trajectory tracking controller. The controller computes error states in longitudinal (ex, ev) and lateral direction (ey, epsi, eomega) and feeds these back linearly via the control inputs ax (acceleration) and delta (steering angle). Feedback terms are combined with feedforward control inputs axs and deltas. Nonlinearity occurs as cos, sin in transformation of position error into coordinates of reference trajectory.
