| 摘 要： | 研究一类可倾瓦支承的单盘非对称转子系统的振动主动控制问题.首先建立了系统的非线性动力学方程,针对主动润滑控制系统设计了BP神经网络PID控制器对转子系统进行振动主动控制.通过计算分析可知,采用基于BP-PID的主动润滑系统能够很好的抑制系统的振幅,使系统在很高的转速时才发生油膜失稳,拓宽转子系统稳定运转的转速范围,在转...

| Abstract: | The vibration active control of an unsymmetrical rotor supported by two tilting pad journal bearings is investigated in this paper.Firstly,the nonlinear governing equation of the rotor system is formulated.Then the BP neural network PID controller is designed with regard to the active lubricated control system is applied to suppress the vibration of the concerning rotor system.After calculation and analysis the persuasive results are obtained.The vibration amplitude of the rotor system is greatly reduced by... |
