摘要
为了有效改善发动机怠速工况下经济性与排放性,考虑怠速工况的非线性、时变性和不确定性等因素,采用怠速Fuzzy-PID控制算法,利用Simulink和Stateflow工具对Fuzzy-PID发动机怠速控制系统进行建模仿真.结果表明该Fuzzy-PID控制器,有良好的实时性、抗干扰性和鲁棒性.同时为解决控制系统的实时性能,在硬件设计上采用功能强大的可编程定点DSP控制芯片TMS320F2812,来实现信号处理与控制功能.
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.
