摘要

低压铸造液面加压系统的模型具有不确定性和时变性。研究表明

用Ziegler Nichols稳定边界法设计其控制系统时

不能确保满足所要求的性能指标

而采用约束优化法可较好处理模型的不确定性和满足所需的性能要求。

Abstract

There are uncertainty and time-variation in the model of filling system in low-pressure die casting. Research results showed that the control system designed by Ziegler-Nichols oscillation method can insurely meet the requirements for specified performance while in turn

can better deal with model uncertainty and meet the requirements.
