In this paper a simulation model is described which encompasses the effects of the bypass air valve, spark advance and load on combustion generated torque including cycle by cycle variations. A model predictive control scheme is developed for the idle bypass valve and spark advance. The idle speed control algorithm is based on estimating the magnitude of the torque disturbance and using model predictive control for the bypass valve duty cycle, while minimizing the transient effects of the disturbance by controlling the spark advance. Simulation results are presented to demonstrate the effects of factors such as levels of spark offset from MBT at idle and feedforward load previews. Compensation of the effects of cyclic variation in combustion torque is also implemented in the controller Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
