摘要：

Tractor draught control systems may be regarded as automatic regulators employing negative feedback. The problem of draught control is defined in control theory terms, in which it is shown that the implement itself forms an element in the loop. The paper describes an apparatus for determining the transfer function of an implement, information which is necessary if quantitative predictions of the dynamic behaviour of a draught control system are to be made. The apparatus is shown to have a second useful function in providing a standard input disturbance for evaluating the performance of draught control systems in general. © 1969.
