On-Line Adaptive Control of a Farm Tractor by Compensation of Parameter Variations [link]Paper  doi  abstract   bibtex   
An adaptive control technique for the control of a farm tractor during low levels of excitation and at low velocities is presented. An analysis of the data is conducted to determine when it is safe to adapt. A cascaded Kalman Filter is presented to estimate the slope of the DC gain of the steer angle to yaw rate transfer function with respect to velocity and to provide faster updates of position. Given this parameter, the controller gains will be scheduled based on a lookup table of predetermined values that were calculated from system identification tests.
