摘要
采用标准[m/n]Padé有理函数逼近时滞因子的方法进行控制对象的模型降阶,并基于位移无静差ITAE最优传递函数,设计了两种时滞系统次优控制器。以双容时滞系统为仿真对象,比较研究表明,基于全极点标准[m/n]Padé有理函数逼近设计的次优控制器获得最佳控制效果。
Dead-time factor is approximately expressed in a standard Pad-type rational function in order to reduce the model orders; sub-optimal controllers based on zero-displacement-error integrated time absolute error （ ITAE ） optimum transfer function are presented. Taking an example of the second order dead-time system, algorithmic simulations are made ; and results show that all-pole standard Pad -type approximation can get an ideal control effect.
