Abstract
Stability is an important consideration in the operation of a three-point hitch control system. The equations are developed and stability evaluated by the Nyquist criterion for an actual system. The general solution for transfer functions is eliminated; instead, the equations that describe the system are written in matrix form. Digital computer solutions of the matrix written in complex numbers provide data points for the Nyquist diagram.
