基于MATLAB的直流调速数字控制系统的分析和设计

摘要

直流调速系统的数字化控制已得到广泛应用。文中简单介绍了直流调速系统数字控制的特点和直流调速系统模型的建立,重点介绍了数字PI控制器和利用Z域根轨迹的设计方法,以及用MATLAB进行了设计过程的仿真和稳定性、动态特性的分析。%Digital control of DC speed control system is widely used.This paper briefly describes digital control features of the DC drive system and DC speed control system model,mainly introduces the digital PI controller and the method of Z domain root locus design,then simulates the design procession by MATLAB and analyzes the stability and dynamic characteristics.
