Claim 15:
16. A controller comprising:
a processor; and
a memory to store computer program instructions for adjusting a height of an implement mounted on a body of a vehicle as the vehicle travels over a terrain, the computer program instructions when executed on the processor cause the processor to perform operations comprising:
receiving sensor data from a set of sensors disposed on the vehicle;
determining a trajectory associated with the vehicle based on the received sensor data;
estimating a profile of the terrain based on the determined trajectory associated with the vehicle;
detecting a ditch in the terrain and determining compensation values for adjusting the height of the implement based on the estimated profile of the terrain to compensate for the detected ditch; and
transmitting one or more control signals to one or more actuators for adjusting the height of the implement based on the determined compensation values, wherein transmitting one or more control signals to one or more actuators for adjusting the height of the implement based on the determined compensation value comprises:
combining initial error values for achieving a target terrain surface with the determined compensation values to generate final error values; and
generating the one or more control signals for adjusting the height of the implement according to the final error values.
