基于三阶最佳设计法的串联校正器的设计

Design of series corrector based on the third-order best design

目前在工程实践中,对线性定常控制系统常用的3种校正方法有串联校正、反馈校正和复合校正,而三阶最佳设计法是在串联综合校正法的基础上,按照最佳性能的要求来设定相应的PID控制器,使得期望特性能进一步的规范化和简单化,最终能够实现一定要求的控制规律。通过仿真结果表明,这种设计方法易于实现,而且大大地改善了系统的控制性能。

There are three correction methods which are the series correction, feedback correction and composite correction usually used for linear time - invariant control system in the engineering practice currently. The third - order best design is based on the series synthetic correction method ,in accordance with the best performance requirements to set the appropriate PID controller, making the desired properties more standardized and easier, and eventually be able to achieve certain requirements of control law. The simulation results show that this design is easy to practice, but also greatly improve control performance of the system.
