【摘要】：当前节能控制方法通常通过建立大功率液压机械传动系统的准确数学节能控制模型实现,但在实际应用中,被控对象的准确数学模型很难建立,不仅效率低下,且影响节能控制性能。为此,提出一种新的大功率机械传动系统的高效节能控制方法。介绍了典型的大功率液压机械传动系统图,获取大功率液压机械传动系统在以外界负载为输入,以负载转速为输出的传递函数,得到通过控制发动机转速可达到节能控制目的的结论,在此基础上,通过具有自学习和自适应能力的单神经元建立单神经元自适应智能节能控制器,对大功率液压机械传动系统进行高效节能控制。实验结果表明,所提方法节能控制性能优越,且效率高。
[Abstract]:The current energy-saving control method is usually realized by establishing the accurate mathematical energy-saving control model of the high-power hydraulic mechanical transmission system. However, in practical application, the accurate mathematical model of the controlled object is difficult to establish, and it is not only inefficient, but also inefficient. And affect the performance of energy saving control. Therefore, a new method of high-efficiency energy-saving control for high-power mechanical transmission system is proposed. This paper introduces the typical high-power hydraulic mechanical transmission system diagram, obtains the transfer function of the high-power hydraulic mechanical transmission system with the external load as the input and the load speed as the output. It is concluded that energy saving control can be achieved by controlling engine speed. On the basis of this, a single neuron adaptive intelligent energy-saving controller is established by single neuron with self-learning and adaptive ability. The high-efficiency and energy-saving control of high-power hydraulic mechanical transmission system is carried out. The experimental results show that the proposed method has superior control performance and high efficiency.
