摘要
磁悬浮薄壁转子是有望实现热力机械高转速与高效率的新型结构,高温热交变载荷可导致薄壁转子的柔性变形与激振,有效的转子系统振动控制是此项新技术推广应用的重要保证,但目前尚缺少相关的结构分析与抑振控制方法。为此,研究建立了薄壁转子-分布式电磁执行器系统动力学模型,差动控制的电磁执行器建模方案可抑制高温热交变环境下薄壁转子的热致振动;通过设计模糊控制器,将高温热交变载荷与模糊规则关联,提出磁悬浮薄壁转子系统的高温热交变自适应模糊控制方法。研究结果表明,高温热交变下磁悬浮薄壁转子系统可自适应调节控制器参数,有效抑制了薄壁转子的热致振动。
The magnetic levitation thin-walled rotor is a novel structure for achieving high rotational speed and high efficiency in thermal machinery.High time-varying temperature can cause flexible deformation and vibration excitation of thin-walled rotors.Effective vibration control of the rotor system is an important guarantee for the widespread application of this new technology,yet relevant structural analysis and vibration suppression methods remain lacking.This paper establishes a dynamic model of the thinwalled rotor integrated with a distributed electromagnetic actuator system.The modeling scheme for the differential control actuator can suppress thermal-induced vibrations of the thin-walled rotor in a high time-varying temperature environment.By designing a fuzzy controller that associates high time-varying temperature with fuzzy rules,we have proposed an adaptive fuzzy control method for the magnetic-levitation thin-walled rotor system.The research results show that under high time-varying temperature,the magnetic-levitation thin-walled rotor system can adaptively adjust the controller parameters,which effectively suppresses the thermal vibration of the thin-walled rotor.
