Fuzzy PI Control Strategy of the Air Bleeder Valve on SIMULINK

Abstract

In order to solve cylinder outbreak problem of high pressure, the blowoff system has been added at transformation process from conventional turbo diesel engine to sequential turbocharing diesel engine. Set up air bleeder valve model of diesel engine sequential turbocharing high condition based on SIMULINK software platform and the air bleeder valve regulated by fuzzy PI control strategies, when the stable operation and in low load conditions of diesel engine, analyses the burst control effect as increase the amount of fuel delivery at different situation. The simulation results show that the model has fast response, high control accuracy and good control effect of high burst pressure, achieve control of diesel engine performance, fuel economy and reliability.
