A method and apparatus for controlling the motor output speed of a variable displacement hydraulic motor are disclosed. The method may include determining a value indicative of a motor output speed, determining a value indicative of a desired motor output speed, determining a desired position of a control valve using a nonlinear feedback control law, and controlling the motor output speed as a function of the control valve position, wherein the nonlinear feedback control creates a first order system response.
