A mobile machine having a chassis, a plurality of ground-engaging elements, a plurality of 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 guidance path along a ground surface. The controller is configured to generate a first set of control values for driving the machine according to a first heading based on a reference heading error of the machine and generate a second set of control values for driving the machine according to a second heading based on a distance heading error of the machine, determine a weight scheme for the first set of control values and the second set of control values dependent on a distance of the machine from the guidance path, combine the control signals using the weight scheme and drive the machine using the combined control signals.
