“…O ganho integral é definido em função do ganho proporcional pela equação (5). (5) Como os ganhos Integral e Proporcional dependem do fator , que é função da rotação do motor, seus valores são pré-calculados através das equações (3) e (5) em intervalos de 100 RPM, utilizando o tempo de resposta desejado de 2 segundos.…”

RESUMOO sistema de controle do torque do motor tem um papel crítico em um veículo automotor, uma vez que o motor precisa atender à demanda solicitada pelo motorista de maneira mais rápida e estável possível. O torque produzido pelo motor é uma consequência da pressão de combustão desenvolvida no interior do cilindro, que é relacionada ao avanço de ignição. Logo é necessário o controle correto da mistura entre ar e combustível e do avanço de ignição, para se obter a máxima pressão de combustão. Porém diferentes combustíveis e suas misturas não possuem os mesmos parâmetros ótimos para o avanço de ignição e tempo de injeção. O presente trabalho propõe o controle do avanço de ignição e do tempo de injeção em malha fechada de um motor bi combustível, a fim de se aperfeiçoar o torque de saída do motor em função da composição do combustível utilizado. A porcentagem de etanol presente no combustível é obtida através de um sensor de composição. A eficiência do sistema em corrigir seus parâmetros em função da composição do combustível e os parâmetros de torque e potência são analisados. INTRODUÇÃO

“…Among them, the very recent ones are presented in Pepe and Jiang (2006) Adaptive Posicast Controller (APC) is developed for linear time-invariant systems with input time delays (Niculescu and Annaswamy (2003)) and later extended for a larger class of systems (Yildiz et al (2010a)). Due to its simple structure it has been one of the rare examples of adaptive controllers that is successfully implemented in an industrial setting (see Yildiz et al (2010bYildiz et al ( , 2011.

Adaptive Posicast Controller that is robust to delay-mismatch is introduced in this paper. Inspired from a recent result on guaranteed delay margins in adaptive control, the original adaptive laws of the above mentioned controller are modified using projection to compensate the uncertainty in the input delay. It is conjectured and shown in simulations that even though the assumed upper bound for the delay value is exceeded, Adaptive Posicast Controller with projection algorithm keeps all the system signals bounded.

Abstract. For port-injected gasoline engines, an innovative strategy of transient fuel-film compensation is proposed to eliminate the impact of fuel-film dynamic effects and improve the transient air fuel ratio control accuracy. A combined fuel-film model composes of a long-term fuel-film and a short-term fuel-film was established. A transient fuel-film compensator model was analyzed in detail. The respective term of the fuel-film model is calculated by a share factor. The decay coefficients control the fuel compensation quantity and the active time. The validity of above models were verified though engine bench tests. The results show that this new strategy can effectively suppress the λ offset during engine transient condition, the transient lambda deviation is less than 5% and stabilized within 1 second.
