dSPACE在发动机硬件在环仿真中的应用

Using four-cylinder spark ignition engine model, one can know the quality of the controller model, by means of practicing the specific method of doing experiment based on dSPACE real-time simulation system. It includes carrying out the closed-loop off-line simulation experiment which is based on MATLAB/Simulink, creating ControlDesk test interface, completing application program compiles, connection, code generation, download, and adjusting the PI parameters to implement real-time simulation experiment based on dSPACE. As it turns out, the engine speed just has little change and it can be returned to normal only in a short time under the load torque disturbance.
