Linear Stage - Position Control Methods

Position Control Methods

The position of the moving platform relative to the fixed base is typically controlled by a linear actuator of some form, whether manual, motorized, or hydraulic/pneumatic. The most common method is to incorporate a lead screw passing through a lead nut in the platform. The rotation of such a lead screw may be controlled either manually or by a motor.

Famous quotes containing the words position, control and/or methods:

    They aroused me to a determination to understand more fully the position of women, and the character of those men who talk so much of the need of our being “protected”Mremoving from us, meanwhile, what are often the very weapons of our defence [sic], occupations, and proper and encouraging remuneration.
    Harriot K. Hunt (1805–1875)

    Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.
    Jean François Lyotard (b. 1924)

    We are lonesome animals. We spend all our life trying to be less lonesome. One of our ancient methods is to tell a story begging the listener to say—and to feel—”Yes, that’s the way it is, or at least that’s the way I feel it. You’re not as alone as you thought.”
    John Steinbeck (1902–1968)
