dc.description.abstract [EN] This work presents a hybrid modeling methodology based on dynamic response, filtering and identification techniques, in order to determine a ball mill representative model. In essence, we have provided models for electrical drive, mechanical reduction and load, without the need for physical decoupling. The electrical parameters are determined using state variable filtering, linear regression and recursive least square techniques. The mechanical parameters are identified considering the system acceleration time. A final adjustment stage considering the parameters set, is carried out using the nonlinear least squares method. Based on the ball mill complete model, a load torque estimator is proposed, using high-pass filters, and a load torque estimate. The numerical simulations, under different operating conditions, show suitable approximation with experimental results. Therefore, the proposed hybrid methodology, based on both dynamic modeling and signal analysis, has the potential to assist in the design for supervision and control systems of a ball mill. es_ES
dc.description.abstract [ES] Este trabajo presenta una metodología híbrida de modelado basada en técnicas de respuesta dinámica, filtrado e identificación, considerando el dominio del tiempo y la frecuencia, para determinar el modelo representativo de un molino de bolas de acoplamiento fijo. Se proponen modelos para el accionamiento eléctrico, reductor mecánico y carga, sin la necesidad de desacoplamiento físico. Los parámetros eléctricos se determinan utilizando técnicas de filtrado de variable de estado, regresión lineal y mínimos cuadrados recursivos, y los parámetros mecánicos se identifican considerando solo el tiempo de aceleración del sistema. Se realiza un ajuste final del conjunto de parámetros mediante la técnica de mínimos cuadrados no lineales. Basado en el modelo completo del molino, se propone un estimador del par de carga, utilizando filtros de paso alto, y se presenta una estimación de la cantidad de carga del molino. Las simulaciones numéricas del modelo determinado, en diferentes condiciones de operación del molino, muestran una buena aproximación con resultados experimentales. Por lo tanto, la metodología híbrida propuesta, basada tanto en el modelado dinámico como en análisis de señales, presenta potencial para ayudar en el proyecto de procesos de supervisión y control del molino de bolas de acoplamiento fijo. es_ES
