Servo: Servo Data

Description

This data set is from a simulation of a servo system involving a servo amplifier, a motor, a lead screw/nut, and a sliding carriage of some sort. It may have been on of the translational axes of a robot on the 9th floor of the AI lab. In any case, the output value is almost certainly a rise time, or the time required for the system to respond to a step change in a position set point. The variables that describe the data set and their values are the following:

[,1]	Motor	A,B,C,D,E
[,2]	Screw	A,B,C,D,E
[,3]	Pgain	3,4,5,6
[,4]	Vgain	1,2,3,4,5

Usage

data(Servo)

Format

A data frame with 167 observations on 5 variables, 4 nominal and 1 as the target class.
