Position controlof robot armusing genetic algorithm based PID controller

الملخص EN

It is known that PID controller is used in every facet of industrial automation.

The application of PID controller span from small industry to high technology industry.

The aim of this paper is to design a position controller of a robot arm by selection of a PID parameters using genetic algorithm.

The model of a robot arm is considered a third order system.

And this paper compares two kinds of tuning methods of parameter for PID controller.

One is the controller design by the genetic algorithm, second is the controller design by the Ziegler and Nichols method.

It was found that the proposed PID parameters adjustment by the genetic algorithm is better than the Ziegler & Nichols’ method.

The proposed method could be applied to the higher order system also.
