非干渉制御理論を用いた機関・CVT・負荷系の燃料消費率最適化制御

抄録

When an automobile has a continuous variable transmission (CVT), it is possible to reduce the fuel consumption by controlling both throttle valve angle and CVT gear ratio simultaneously. The main reason for this is that the fuel consumption of the engine becomes tolerably economical when it runs with an operating condition of low speed and high torque rather than high speed and low torque. But changing the value of the throttle valve angle or CVT gear ratio naturally affects the automobile speed. Therefore control theory such as decoupling control or multi-input output control becomes necessary. Reported here is the optimization fuel consumption control using a decoupling control theory. Also, modelling of the relevant system (engine∼CVT∼load system) was performed for designing the decoupling control system and for simulation studies. The experiments achieved the expected results.
