Abstract

According to the control principle of diesel ECU, the simulation model of diesel control system was constructed with Matlab/Simulink software, which was based on the increment type digital PID control algorithm. The control algorithm and control logic subsystem in the model were established with the basic module library of Simulink, the signal collection and drive subsystem were built with the module of DSPACE RTI RCPU and the system was simulated with the Stateflow tool. Through the RCP model test, the test data of all system parameters were acquired, which verified the real time and reliability of model.
