多变量綫性系統并联校正装置的一种綜合方法
SYNTHESIS OF FEEDBACK CONTROLLERS FOR MULTIVARIABLE LINEAR CONTROL SYSTEMS
-
摘要: 本文给出线性多变量控制系统的一种分析设计方法,将预期特性和实际特性之差视为假想的内部反馈,引入并联校正装置补偿它对系统的有害影响。不同于通常的频率法或根轨迹法,这种方法不用图解,直接对系统的参数及结构进行分析计算,因而准确性较高,对多变量多迴路系统应用比较方便。在国产T615K重型镗床进给系统上进行试验,结果表明用本文的方法综合校正装置是有效的。Abstract: An analytical design method for multivariable linear control systems is proposed.The difference between the expected transfer function and the real transfer function ofa given system is considered as a pseudo internal feedback. The feedback controller isthen introduced to compensate the bad effects of this internal feedback. The effectiveness of this method has been demonstrated in the design of the feedsystem of a heayy duty boring machine.
