Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: This work presents the use of a Lyapunov based adaptive controller optimized by a Genetic Algorithm applied to tuning the parameter that define a fall rating of the error between a reference value (set point) and the output of the system in a simulation environment. The system has been modeled with certain degree of uncertainty with regard of its parameters. The complete system, which include the the Transfer Function of the system being utilized was simulated in Scilab software being the results of the simulations presented.
