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 |
| [,5] | Class | 0.13 to 7.10 |
data("Servo", package = "mlbench")A data frame with 167 observations on 5 variables, 4 nominal and 1 as the target class.
