Abstract :
A performance limit is presented for a system designed to have finite-settling-time while using look-ahead control, under the design requirement that sampled output track both step inputs and ramp inputs with zero error in finite time. This performance limit clarifies the relationship between the least amount of overshoot attainable, the settling-time, the look-ahead horizon, and the time delay of the plant. The optimum design of a preview-controlled finite-settling-time system is discussed
