As mudanças climáticas e a tendência de eletrificação causada pelo uso de energias renováveis incentiva a pesquisa em eletrificação de sistemas e direciona parte do interesse a tecnologias de acionamentos elétricos. Dentre os motores usados em acionamentos modernos, os motores de indução trifásicos mostram-se competitivos dado o seu baixo custo, elevada robustez e maturidade tecnológica. Este artigo explora métodos de controle direto de torque e fluxo, com destaque para controles preditivos, promissores por sua resposta dinâmica rápida e flexibilidade com não linearidades. São analisados resultados experimentais do DTC, PTC, PTC-DSVM e MPTC na mesma bancada. Os resultados demonstram por meio das respostas dinâmica, em regime e THD as diferenças entre estratégias e mostram que a frequência fixa do MPTC não se relaciona diretamente à melhor qualidade de energia no acionamento. O custo computacional também é medido para complemento das análises.

“…Regarding the regenerative braking, the amount of energy that can be saved from the existing trolleybuses under real operating conditions (e.g., during speed reduction intervals or downhill In addition, besides implementing the existing direct vector control (DVC) scheme of the trolleybus asynchronous machine, the direct torque control (DTC), which is widely used for the dynamic control of electric alternating current (AC) machines [12,13], is also considered. Both methods rely on the dynamic model of the machine, though they implement different control logic [14].…”

Abstract:In this work, the electromechanical system of the 8000-series of Athens trolleybuses, based on data provided by OSY S.A., is analyzed. Those data were used to develop a valid model in order to estimate the total energy consumption of the vehicle under any possible operating conditions. In addition, an effort is made to estimate the energy saving potential if the wasted energy-in the form of heat-during braking or downhill courses is recovered (regenerative braking) and retrofitted during normal operation. This process requires the installation of appropriate electrical apparatus to recover and temporarily store this energy amount. Moreover, due to the fact that the main engine of the system is an asynchronous electric machine, its driving scheme is also of interest. This study assumes the current driving scheme, that is the direct vector control (DVC), and proposes an alternative control method, the direct torque control (DTC). Energy consumption/saving calculations highlight the effectiveness of incorporating regenerative braking infrastructure in trolleybuses transportation systems. Finally, a sustainable hybrid energy storage unit that supports regenerative braking is proposed.

The paper deals with the utilization of Kalman filter and fuzzy logic control in induction motor drive with direct torque control (DTC). In order to lower ripple of stator current vector in DTC drive, pulse width modulation technique with high switching frequency is applied. However, the performance of the DTC also depends on the accuracy of both stator resistance and stator current vector. In the paper, the stator resistance and stator current components are assumed to be distorted by Gaussian noises. In order to reduce the effect of noises especially at low speed and very low speed regions, a simple Kalman filter is applied for filtering current components, and fuzzy logic theory is used to increase the flexibility of proportional-integral (PI) compensator in the speed controller of the drive structure. Simulations are implemented in conditions of high-level noises of stator current and stator resistance, and a wide range of load torque. An ITAE-based criterion is utilized to evaluate the performance of drive structures. Results confirmed the expected dynamic properties of the proposed drive structure.
