| Abstract: | To improve economic and emission of engine at idle condition,consider nonlinearity,time degeneration,and uncertainty of idle state,Adopting the idle Fuzzy-PID control algorithm,and using the Simulink and the Stateflow tools,Fuzzy-PID engine idle control system was modeled and simulated.Result indicates that Fuzzy-PID controller has fine real-time performance,anti-disturbance,and better robustness.To achieve real-time performance of the control system,the chip TMS320F2812 which has powerful fixed-point programmabe capacity for DSP control,was used to design the hardware of the system,to achieve signal processing and control function. |
