Laminated Glass UHF-RFID Antenna for Automotive Applications

Abstract

This paper presents a new technique for UHF RFID antenna integration with a great impact on the automotive industry. The antenna has been optimized in HFSS and the prototype has been laminated and measured, in between two thin glass slices. The design takes into account the aspects related to the automotive safety glass, used for the windscreens in front of the automobiles. The paper proposes the use of aluminum sheets for the active element of the antenna together with three glass layers as substrates. This approach exhibits excellent results and could be applicable for vehicle long-range identification (AVI) or for cars tracking and localization.

A Very-Low-Speed Sensorless Control Induction Motor Drive with Online Rotor Resistance Tuning by Using MRAS Scheme

Abstract

A sensorless indirect stator-flux-oriented control (ISFOC) induction motor drive at very low frequencies is presented herein. The model reference adaptive system (MRAS) scheme is used to estimate the speed and the rotor resistance simultaneously. However, the error between the reference and the adjustable models, which are developed in the stationary stator reference frame, is used to drive a suitable adaptation mechanism that generates the estimates of speed and the rotor resistance from the stator voltage and the machine current measurements. The stator flux components in the stationary reference frame are estimated through a pure integration of the back electro-motive force (EMF) of the machine. When the machine is operated at low speed, the pure integration of the back EMF introduces an error in flux estimation which affects the performance torque and speed control. To overcome this problem, pure integration is replaced with a programmable cascaded low-pass filter (PCLPF). The stability analysis method of the MRAS estimator is verified in order to show the robustness of the rotor resistance variations. Experimental results are presented to prove the effectiveness and validity of the proposed scheme of sensorless ISFOC induction motor drive.
