Abstract:
A partir de las dificultades que implica el uso de herramientas del cálculo no entero o fraccional aplicados al modelado y control de sistemas dinámicos, se resuelven dos limitantes en el diseño de sistemas de control de tipo fraccional, la sintonización e implementación de controladores PIλDIμ.
En este trabajo se propone una solución a través de circuitos analógicos programables y reconfigurables al reto de implementar físicamente controladores PID de orden fraccional, se muestra también una herramienta accesible a estudiantes e ingenieros (MATLAB) para realizar la sintonización de este tipo de controladores.
Description:
Currently the PID controller is the most widely used in industry due to its simple structure and relatively easy understanding. This work proposes the introduction of a fractional order PID controller to obtain a more flexible and robust control than the conventional PID, with the inclusion of two additional degrees of freedom. The PI λ DI μ controller has an integrator of order λ and a differentiator of order μ, with λ, μ ∈ (0, 2) allowing to add restrictions and specifications for the tuning process, improving the performance of the system response. In addition, it is proposed the use of reconfigurable devices, such as FPGAs or FPAAs, to make changes in situ. It is also proposed the use of neural networks to estimate the values P, I, D, λ and μ in order to make the system insensible to variations in the plant parameters.
