A modified posicast method of control with applications to higher-order systems

The theory of Posicast control,1‾
_{3 by using a delayed step or steps, permits deadbeat step response from a very lightly damped system. The original development deals primarily with second-order systems, proposes a delay line technique for application of the second step, notes that use of this technique leaves the basic system underdamped, then proposes use of the delay line in a feedback path to damp load disturbances, and finally proposes the use of a tapped delay line for higher-order systems.}
