【摘要】 在分析发动机转速控制原理的基础上,研究了采用步进电动机作为执行机构的发动机油门控制,建立了神经网络优化PID控制的离散数学模型。采用LabVIEW软件对发动机油门控制进行了仿真试验,结果表明,发动机油门控制方法具有良好的动态响应与鲁棒性,超调量为0.018,稳态时的输出误差近似为零。更多还原

【Abstract】 Based on the analysis of the control principle of engine rotary speed,the control of engine throttle by a stepper motor was investigated.The discrete mathematical model optimized by neural network PID control was established.The simulation of the engine throttle control was carried out by the LabVIEW software.The simulated results showed that the excess of the system was 0.018 and the output error of the stable state was nearly zero.The control method of engine throttle has good dynamic response and robustness.更多还原
