Implementación de control de velocidad de un motor dc con controlador pid convencional y difuso p-pi-pid con diferentes tipos de entradas utilizando software labview

Abstract

This project presents the implementation of a conventional and Fuzzy P-PI-PID PID control. The schematics are designed to control the speed of a DC motor that comes in the National Instruments EPC control station where the programming environment is fully realized with LabVIEW software with the Fuzzy Designer control, design and simulation module and whose interaction Physics with the EPC plant is performed using a NI USB-6009 data acquisition card. It is sought with both techniques to control the response of the system to a different input such as square, sine, sawtooth and random wave, and then to compare the regulators observing the marked improvement in the response of the system with fuzzy controller. Finally, it was observed as a result the benefits that regulations can be made quickly, understandably and facing problems, especially when there is no controlled system model or when the model presents an unfavorable non-linear structure, the behavior of a system being simpler. described in linguistic expressions than a mathematical description. Having the limitation that the fuzzy controller must be built based on prior knowledge of the operation and operating experiences of the system, and with greater complexity of the system, the work necessary for the development of a fuzzy controller becomes over-proportional. It is possible to observe that the Fuzzy Controller has a shorter response establishment time and greater robustness since it is not very sensitive to disturbances.
