Evolvable Hardware a New Approach for Control Design TATIANE JESUS DE CAMPOS JOSÉ RAIMUNDO DE OLIVEIRA

Evolvable hardware (EHW) is a technique introduced to automatically design circuits where the circuit configuration is carried out by evolutionary algorithms. This paper shows that the evolutionary approach can discover the concept and learning behavior of the control systems. The system tested is a nonlinear pendulum. Experiments with different processes indicate that the gains obtained with evolvable hardware may provide better responses than those obtained by the classical PID controller whose gains are set by Genetic Algorithms. In this paper the Integral of the Square Error (ISE) criteria was used as performance index to be minimized through applying of Genetic Algorithms and Evolvable Hardware controllers. Analysis and simulation of nonlinear pendulum is provided to demonstrate that the proposed evolvable controller has excellent results. Key-Words: Evolvable Hardware, Control Systems, PID Controller, Evolvable Controller.
