Abstract
An intelligent variable mode control method for variable altitude turbocharging system of diesel engine, including: querying turbocharging pressure MAP chart upon speed and torque demands; reading a target pressure, and correcting it to obtain a corrected pressure; based on adaptive ranges of flow-pressure ratio of turbocharging modes, using fuzzy control algorithms to achieve intelligent selection of turbocharging modes; initializing opening degrees of high- and low-pressure stage bypass valves within adjustment ranges; using neural network fast prediction models to predict turbocharging pressures; using genetic algorithms to fast search bypass valve opening degrees corresponding the target and send them to the valve control unit. The invention achieves turbocharging mode selection and precise turbocharging pressure control during variable altitude operation of diesel engines, and achieves model-based intelligent variable mode adaptive optimization control of variable altitude diesel engine turbocharging systems.
