Model Predictive Control considering disturbances in diesel engine air intake systems

Model Predictive Control (MPC) is applied in order to improve the transient response in diesel engine air intake systems. In actual engines, a steady state error is generated due to disturbances such as the fluctuation of air intake and fuel injection amounts and the modeling error of the systems. This causes target tracking deterioration. In order to cancel the steady state error, we evaluate three compensation methods in simulations and actual transient response tests: a) a method of incorporating the constant disturbance model, b) a method of explicitly incorporating an integrator, and c) a method using a disturbance observer in motion control. We clarify the configuration of MPC effective for improving target tracking performance.
