A mobile machine including a chassis, a plurality of ground-engaging elements, actuators for driving movement of the ground-engaging elements and a controller for controlling each of the actuators to cause the mobile machine to follow a reference path. The controller is configured to implement a cascading control loop for controlling movement of the mobile machine, the cascading control loop including an outer loop and an inner loop. The outer loop is configured to determine a set heading for reducing a distance between the mobile machine and the reference path, the set heading being determined using an error slope parameter. The inner loop is configured to drive the actuators so that the mobile machine follows the set heading determined by the outer loop. The controller is configured to automatically adjust the error slope value so that the rate of change of the set heading does not exceed a maximum yaw rate.
