Input Attenuation Functions Improve Servomechanism Performance

The advent of numerically controlled point-to-point industrial equipment has provided a suitable set of conditions for input attenuation functions to improve the performance of linear servomechanisms. The replacement of a random input by a programmed sequence of events allows the output to have essentially dead beat transient response. The elimination of overshoot and a substantial reduction of settling time, allows a numerical instruction to be completed in less time than normally required. The additional control circuitry is simple, inexpensive, and should not impair the reliability.
