Bode
En este proyecto abordamos la construcción de una interfaz de usuario interactiva para los Diagramas de Bode, herramienta muy utilizada en Ingeniería del Control (Figura 1). El módulo de cálculo ha sido escrito en lenguaje C por Javier Gil Chica, profesor titular del Departamento de Física de la Universidad de Alicante. El código fuente al completo está disponible disponible en la carpeta /src/demo/bode
de la distribución del SDK.
La ventana principal se ha dividido verticalmente en dos partes, mediante un layout(2,1)
(Figura 4). En la parte izquierda tenemos los parámetros P, Q, T, R
y algunos botones. Se han utilizado los sublayouts i_coeffs(4,9)
y i_ranges(3,3)
para agrupar controles. En la zona de la derecha se ubican dos controles de dibujo View para las gráficas y otro sublayout i_sliders(3,3)
con los parámetros I, P, D
.
El re-dimensionado horizontal se realiza íntegramente sobre la celda derecha (gráficas y sliders), manteniendo la zona de parámetros un tamaño horizontal constante. Durante el re-dimensionado vertical crecerán las gráficas con una proporción del 50% cada una. Para la parte izquierda, se ha reservado una celda vacía, que se expandirá horizontalmente, alineando el botón [More Info]
al borde inferior de la ventana.
