Koontz and Bradspies (1972) studied feedback and feedforward control
systems; adapting their model with the inputs, outputs, and control loops used in an NPD portfolio review meeting produces a control systems representation of the Stage-Gate meeting (Figure 1).

produces predictive motor commands that reflect previous reaching history, and feedback control is the ability to make adjustments during the movement based on error detection by the visual and proprioceptive sensory systems [5-7].
A qualitative discussion of mechanisms of feedback and feedforward control
The synthesis procedure, which employs integral feedforward control
, is presented in section III.
Simple feedforward control
only works adequately when the system can be accurately represented with an instantaneous algebraic equation.
A Simple Tool for Disturbance Resiliency Diagnosis and Feedforward Control
systems allow for the use of unskilled labor by ensuring quality and standardization through processes rather than individuals (Fowler, 1999; Morgan, 1992), while feedback control systems leave quality in the hands of workers so that products can be tailored to meet customer needs (Filley and Aldag, 1980).
Many plants already have the assets to do this and some PID blocks have a bias input, making implementing feedforward control
as simple as an adding to a feedback loop.
is linked to the literature on cybernetics (Ashby 1963, Beer 1967).
for competitive advantage: The Japanese approach.
It is associated with the theme of controlling the process not the product and is a form of feedforward control
