Control apparatus for a horizontal boring tool is described which drives a
boring lance via boring rods. The tool includes an input interface for
receiving actual values of controlled variables of the horizontal boring
tool, and an output unit for issuing control signals for controlling the
horizontal boring tool. Between the input interface and the output unit is
provided a fuzzy control unit which determines the control signals for
activation of the horizontal boring tool from the actual values of the
controlled variables and the desired values for the controlled variables
by fuzzy logic while taking into account heuristic process values. The
control apparatus permits automatic operation of the horizontal boring
tool with good course steering and high precision.
