电控机械式自动变速车辆发动机转速控制系统的研究

摘要

Aiming at the problems of traditional PID control algorithm is difficult to achieve the optimum parameters in the engine speed control, a neuron adaptive PID algorithm is proposed, to implement closed-loop control for engine speed. Because neuron adaptive PID can adjust its control parameters on-line, the quick tracking control of engine speed can be implemented when the target engine speed changes. The experiment results show that the quick response and good control accuracy is obtained for engine speed control with neuron adaptive PID algorithm.%针对传统PID算法在发动机转速控制中难以实现最佳参数问题,提出了利用神经元自适应PID算法对发动机转速进行闭环控制.由于神经元自适应PID 可以在线调整 其参数值,因此当发动机目标转速发生变化时可以通过改变控制参数来实现转速的快速跟踪.实验结果表明使用神经元自适应PID算法对发动机转速控制可以达到快速响应和较高精度的控制效果.
