La sincronizacion y control de senales caoticas es una activa area de investigacion por sus posibles aplicaciones en telecomunicaciones y transmision de senales [1, 2, 3, 4]. En el presente trabajo se estudia un sistema de comunicacion basado en la sincronizacion de dos sistemas no lineales caoticos, cada uno modelado a partir de las ecuaciones de movimiento de un pendulo forzado amortiguado y que se encuentran en el mismo punto de operacion del espacio de parametros. Synchronization and control of chaotic signals is an active research area because of its applications in telecommunications and secure signal transmission [1,2,3,4]. In this work a communication system based in the synchronization of two chaotic nonlinear systems, each one being modeled by the motion equations of a driven damped pendulum and operated in the same parameter space region is shown. Two communication channels were used: the first one for the synchronizing signal and the second one for the sent message. By using two channels the initial conditions sensibility problem is solved. In the receiver system a feedback loop as a proportional controller is used in order to drive quickly the error between the decoder and encoder states to zero. The last two facts make the system to be robust to external pertubative signals such as noise in the communication channels.
