Chinese Abstract

根据铝合金轮毂的铸造工艺要求,采用了前馈-模糊控制的方法实现低压铸造的压力跟踪,采用PI控制的方法实现轮毂低压铸造要求的稳态性能。应用实践表明,所研究的控制系统不仅实现了压力跟踪阶段的误差在20 mBar以内,而且在稳态阶段的压力误差也在20 mBar以内。

English Abstract

The low pressure die casting is a kind of molding technics which is widely used currently. On the request of molding technics of aluminium alloy wheel, this paper studies the feed forward-fuzzy method for low pressure die casting pressure tracking and the P1 method for the steady-state control. The application in practice shows that not only the transient-state error but the steady error of the control system are less than 20 mBar.
