【摘要】 由于大型精密构件在提升过程中,环境载荷和提升不同步引起的振动是影响提升构件安全性和稳定性的最主要因素,初步设计了大型提升对象的振动主动控制大型试验台架,并用MATLAB进行仿真模拟。由于大型提升构件的振动控制模型无法准确得到,加之环境载荷多变,因此设计了模糊自适应PID控制系统,通过对PID控制器参数的整定,使它适应随机环境载荷的影响和提升高度的不断变化。通过仿真分析可知,模糊自适应PID控制系统可以起到很好的控制效果,具有很强的鲁棒性、稳定性和安全性,具有一定的应用前景。更多还原

【Abstract】 ;During the process of lifting large-scale components, the vibrations due to environmental loads and asynchronous liftings are the major factors affecting the safety and stability. A test rig is built to testify an active anti-vibration system, which is simulated by using MATLAB. This paper presents an Adaptive Fuzzy Control approach to suppress the vibration of lifting system. The results from tests and simulations all indicate the method could improve the control performance and robustness of the Anti-Vibration.更多还原
