Lehiaketa motor baten atzealde-suspentsio sistema doigarri baten elementuen diseinua

[EU]Proiektu hau lehiaketa motor baten atzealde-suspentsio sistema doigarri baten elementuen diseinuan datza. Luzeran erregulagarria izango den tirantea eta suspentsio triangelua diseinatu eta optimizatuko dira. Diseinuak ahalik eta pisu txikiena izatea ahalbidetzen duten makinen elementuak (errotulak eta errodamenduak) aukeratuko dira. Lanaren garapenerako Motostudent izeneko lehiaketatik hartutako datu errealak erabiliko dira. Suspentsio sistemaren diseinua Creo2.0 (lehengo Pro-Engineer) software-arekin egingo da. Bestalde, beste software batzuk ere erabiliko dira, hala nola, Working Model 2D eta ANSYS, sistemaren analisia errazteko.

Diseño de un sistema de suspensión progresiva Full-Floater

[ES]El objetivo del trabajo consiste en diseñar y dimensionar un sistema de suspensión progresiva tipo Full-Floater para una moto de competición. Se debe hacer un diseño que se adapte a unas condiciones de progresividad y rigidez para un bloque amortiguador dado. Para el desarrollo del trabajo se suministran datos reales tomados de la competición Motostudent. El desarrollo se realiza mediante el software PTC Creo 2.0.

A Real-Time Sliding Mode Control for a Wind Energy System Based on a Doubly Fed Induction Generator

In this paper, a real time sliding mode control scheme for a variable speed wind turbine that incorporates a doubly feed induction generator is described. In this design, the so-called vector control theory is applied, in order to simplify the system electrical equations. The proposed control scheme involves a low computational cost and therefore can be implemented in real-time applications using a low cost Digital Signal Processor (DSP). The stability analysis of the proposed sliding mode controller under disturbances and parameter uncertainties is provided using the Lyapunov stability theory. A new experimental platform has been designed and constructed in order to analyze the real-time performance of the proposed controller in a real system. Finally, the experimental validation carried out in the experimental platform shows; on the one hand that the proposed controller provides high-performance dynamic characteristics, and on the other hand that this scheme is robust with respect to the uncertainties that usually appear in the real systems.
