自动控制原理课程中稳态误差求取方法之探索

Research of Solving Methods for Steady State Error in Course of Automation Control Theory

稳态误差是控制系统的三大技术参数之一。主要围绕线性连续系统在典型输入信号作用下的稳态误差求取方法展开研究,针对输入信号形式以及输入信号位置的不同,提出3种解题思路和方法。经过几年的教学实践,这种因题而异的解题思路大大激发学生学习的兴趣、降低解题的错误率、提高解题的速度。实践证明,稳态误差求取的这3种解题方法是可行、有效的、值得推广的。

As steady state error is one of the three technical parameters in control systems, the approach to solving steady state errors in linear continuous systems under typical input signals is researched in this article. Because of the type and position of input signals, the author brings forward three solving methods. After these years of practice, this solving idea has inspired the student’s learning interest greatly and has also reduced the error rate and improved the speed in the student’s solving process largely. Practice has proved that three solving methods is feasible and effective and is worth of spreading.
