Control Predictivo basado en Modelo de variables complejas para el seguimiento de señaales sinusoidales en inversores trifásicos

Abstract

En este documento se presenta la implementación de un algoritmo basado en Control Predictivo por Modelo para el control del voltaje su- ministrado por un inversor trifásico sobre cargas lineales. Concretamente, se presenta una modificación a este de MPC para el seguimiento de re- ferencias sinusoidales trifásicas modeladas con números complejos. Para ello, se explican primero las bases teóricas del trabajo, como son el fun- cionamiento de una fuente trifásica ideal, el método MNA para el cálculo algorítmico de funciones de transferencia de circuitos lineales, la Transfor- mación de Clarke o de coordenadas αβ para la simplificación de sistemas trifásicos equilibrados, la obtención de modelos complejos de una variable a partir de modelos eléctricos en el espacio αβ, y el Control Predictivo por Modelo, el cual es un algoritmo para el cálculo de ganancias en el control en espacio de estados. Con las bases sentadas, se explica la modi- ficación realizada al MPC convencional, que consiste en una modificación al integrador que este incluye en el modelo usado para el cálculo de las ganancias del controlador. Después, se explica al detalle como obtener di- chas ganancias con esta nueva versión de MPC, para luego llevar a cabo varias simulaciones en MATLAB para ver su desempeño. Finalmente, se prueba dicho controlador en un modelo real
