混合动力电动汽车发动机转速智能控制系统设计

发动机是混合动力电动汽车动力设备的心脏,为了保证混合动力电动汽车可以快速稳定地运行,需要对其转速智能控制系统进行设计。使用当前控制系统智能控制混合动力电动汽车发动机转速时,无法快速检测到发动机转速,难以达到最佳的智能控制结果。为此,本文提出一种基于软切换的Bang Bang－神经网络PID的混合动力电动汽车发动机转速智能控制系统设计方法。混合动力电动汽车发动机转速智能控制系统以Mcs一51系列8751单片机为核心系统,检测混合动力电动汽车发动机转速的数字信号,同时控制D/A模拟信号的输出,并在LED显示器上显示发动机转速数字信号,以PWM调制器放大混合动力电动汽车启动时发动机产生的PWM波,将放大后的PWM波供给电力发动机,再以分频填充脉冲装置测量混合动力电动汽车发动机转速,通过Bang Bang－神经网络PID算法计算出混合动力电动汽车发动机转速误差,达到实时控制混合动力电动汽车发动机转速的效果。实验仿真证明,所提设计方法保证了发动机转速的快速性和平稳性。
