Discrete modeling of nonlinear unvaried dynamic systems with first-order approach
This article shows a method to obtain a black box dynamic model of a nonlinear univariated system. A formal theoretical deduction is proposed to justify the procedure and steps to be followed are reported in order to implement them to any univariated system.

A formal theoretical deduction is proposed to justify the procedure and steps to be followed are reported in order to implement them to any univariated system. Two examples are used to validate the explained methodology: a simulated nonlinear univariated system and a direct current motor separately excited.

Se hace una deducción teórica formal para justificar el procedimiento y se enuncian los pasos a seguir que pueden ser aplicados a cualquier sistema univariado. Dos ejemplos son utilizados para exponer la validez de la metodología: un sistema simulado univariado no lineal y un motor de corriente continua con excitación independiente. En ambos casos, el modelo discreto obtenido por ecuación en diferencias es una linealización por segmentos de la función algebraica entre las variables de entrada y salida. Los parámetros de dicha ecuación son dependientes de la variable de entrada. La metodología expuesta puede ser incluida como práctica experimental en cursos de ingeniería sobre teoría de control, modelamiento y simulación de sistemas dinámicos.Este documento apresenta um método para obter o modelo dinâmico de caixa preta de um sistema univariado não lineal.

| description |
This article shows a method to obtain a black box dynamic model of a nonlinear univariated system. A formal theoretical deduction is proposed to justify the procedure and steps to be followed are reported in order to implement them to any univariated system. Two examples are used to validate the explained methodology: a simulated nonlinear univariated system and a direct current motor separately excited. In both cases, the model obtained by difference equations is a segmented linearization of the algebraic function between both input and output variables. Parameters in that equation are dependent of input variable. The explained methodology can be included as an experimental practice in engineering subjects about control theory, modeling and simulation of dynamic systems. |
