机械元动作装配单元可靠性是整机功能可靠性的重要构成,元动作单元工作过程中振动异常是导致其故障频发的重要因素.因此,采取有效的振动控制策略对降低元动作单元运行故障、提高单元可靠性和整机性能具有良好的工程意义.结合主动控制思想采用简易、精准的作动装置建立了一种智能的振动控制系统.为了提升控制系统中智能位移作动器的进给精度,设计了变论域自适应模糊PID控制器,并通过仿真分析了控制系统的可行性.仿真结果表明,变论域自适应模糊PID控制器下的系统响应具有极低的超调量、较少调整时间和趋于零的稳态误差.此项研究为提高机械产品使用可靠性提供了一种新的振动控制技术手段.
Research on Variable Universe Adaptive Fuzzy PID Vibration Control System of Mechanical Meta-Action Unit Driven by Reliability
The reliability of mechanical meta action assembly unit is an important component that affects the functional reliabil-ity of the whole machine.The abnormal vibration in the working process of the unit is an important factor leading to frequent fail-ure rate.Therefore,it is of great engineering significance to take effective vibration control strategy to reduce the operation failure of the unit and improve the reliability and performance of the whole machine.Combined with the idea of active control,an intelli-gent vibration control system is established by using simple and accurate actuator.In order to improve the feed accuracy of intelli-gent displacement actuator,a variable universe adaptive fuzzy PID controller is designed,and the feasibility of the control system is analyzed by simulation.The simulation results show that the system response under the variable universe adaptive fuzzy PIDcon-troller has very low overshoot,less adjustment time and steady-state error tending to zero.This research provides a new control technology for improving the reliability of mechanical products.
