Abstract
A unit and a method for determining gains of a PID (Proportion, Integral, Differential) controller using a genetic algorithm. A genetic algorithm tuning unit decodes an output value from an object system extracted by a feature extracting unit, and generates a first population including a random binary string. Then, the first population is normalized in a given ratio to measure a PID gain converting fitness with respect to the first population. Thereafter, the normalized first population is compared with the decoded value to determine whether it is a user's desired value. If the desired value is obtained, the genetic algorithm tuning unit generates PID gain control signals with respect to the resulting value, which are supplied to the PID controller to tune PID gains.
