| 摘 要： | 燃气发动机混合气中煤层气浓度、压力或温度发生变化时,空燃比随之发生变化.为了控制发动机空燃比,使其在煤层气理论空燃比17.2附近波动,提出了空燃比控制策略.对基于PID控制和CMAC PID并行控制的两种策略进行了仿真,由仿真结果看出,后者较前者稳态误差小,控制精度高.

| Abstract: | When the concentration,pressure or temperature of methane changes,the A/F ratio will change accordingly.In order to control the A/F,a control method was put forward.Both the method based on PID control and the method based on the CMAC and PID parallel control were simulated.As can be seen from the simulation results,the control precision was improved and the stedy-state error was reduced by the latter method. |
