Modelado matemático, simulación, análisis y control de un sistema hidráulico interactivo-tres tanques en serieMathematical modeling, simulation, analysis and control of an interactive hydraulic system-three tanks in series Laura V. Medina S, Gloria A. Contreras G, Olga L. Roa B, Hector M.Vega Resumen n éste trabajo se modela y analiza un sistema hidráulico que está conformado por tres tanques en serie, con un fluido de baja viscosidad y tuberias poco rugosas, sistema interactivo dinámico no lineal; bajo la metodología de sistemas dinámicos. El objetivo es llegar a presentar un control lineal por realimentación del estado basado en el modelo lineal diagonalizado, que mantiene al sistema no lineal controlando los caudales de salida; para esto se hace uso de diferentes métodos de la teoría de control usando el programa de MatLab y su herramienta Simulink y en este se implementa el método numérico para solucionar ecuaciones diferenciales llamado Runge Kutta y el modelo matemático del sistema no lineal para luego analizar su comportamiento a través del tiempo, linealización del sistema y análisis de sensibilidad, presentación de la forma canónica diagonal del modelo linealizado entre otros.Palabras clave: control lineal, sistemas dinámicos, sistema interactivo, sistema lineal, sistema no lineal, Simulink/MatLab, sistema hidráulico. Abstractn this work, a hydraulic system is modeled and analyzed. It consists of three tanks in series, with a fluid of low viscosity and slightly rough pipes, interactive non-linear dynamic system; under the dynamic systems methodology. The objective is to arrive at presenting a linear control by state feedback based on the diagonalized linear model, which keeps the non-linear system controlling the output flows; For this, different methods of control theory are used using the MatLab program and its Simulink tool, and in this the numerical method to solve differential equations called Runge Kutta and the mathematical model of the nonlinear system is implemented to later analyze its behavior over time, linearization of the system and sensitivity analysis, presentation of the diagonal canonical form of the linearized model among others.
