| 摘 要： | PWM控制技术在电力电子技术领域得到了广泛的应用,在过程控制领域,PWM控制方式也具有特殊的优势。本文利用MATLAB仿真技术对采用PWM控制方式的控制系统进行了研究。研究的被控对象为过程控制中常见的一阶惯性和二阶惯性。本文中给出了部分的仿真图形和数据,研究的结果表明当PWM信号的周期与被控对象大时间常数的比值T/T0在0.1～0.2之间时,PWM控制的各项性能指标都比较合适。并且随着T/T0的增大,系统的超调、调节时间、稳态误差以及纹波将逐渐变大。

| Abstract: | The PWM control technique has been widely used in the field of electronic and electrical. In the process control field, PWM control method also has particular advantages. The MATLAB simulation technique is made use of to study the PWM automatic control system in this paper. The plants in the system are one order and two order which are common in the process control. Simulation figures and data are presented to show the relations between the PWM period and controlling performance such as response speed, static error, dynamic error and ripple etc. |
