摘    要:高阶系统由于其本身的性质,使得控制它变得很困难。为了控制一类典型的可用传递函数描述的高阶对象,用二阶线性自抗扰(LADRC)控制器对高阶系统进行参数整定。将已整定好的高阶系统作为基准系统,通过时间尺度概念将基准系统参数转换为需要控制的新的高阶系统的参数,使得新系统具有基准系统的响应特性。该方法能方便、快捷地算出新系统的参数,通过仿真证明了该方法的可行性,具有广泛的参考价值。

关 键 词:时间尺度  二阶线性自抗扰  高阶系统  基准系统

Abstract:Higher order system is difficult to control due to its own nature.In order to control a class of typical high order objects which can be described by transfer function,the second-order linear active disturbance rejection (LADRC) controller was used to set the parameters of high order system.The adjusted high-order system will act as the benchmark system.The parameters of benchmark system are converted to parameters of new high order system by using the conception of time scale,making the new system have the response characteristics of benchmark system.This method can calculate the parameters of the new system conveniently and quickly. The simulation result proves that it is feasible and has a wide range of reference values.
Keywords:Time scale  Second order linear active disturbance rejection control(LADRC)  High order system  Benchmark system
