摘　　要：基于系统期望开环伯德图,阐述了滞后环节和超前环节的有利和不足。以一个系统的完整校正过程为例,给出补偿环节的类型和幅穿频率的选择,提供环节参数的公式计算,使读者能够对系统串联校正这个复杂工程问题获得更深入和全面理解。通过对“自动控制原理”课程中频域串联校正的教学内容和思路、改革措施和实践效果进行探讨,为频域串联校正教学提供一个参考。Based on the expected open-loop Bode diagram,the advantages and disadvantages of lag and lead corrector are described.Taking the complete correction process of a system as an example,the selection of corrector type and its gain crossover frequency are analyzed,and the calculation formula of corrector parameters is also given.Based on these,the readers can gain a more in-depth and comprehensive understanding of the complex engineering problem.The teaching contents and ideas of series correction within frequency domain in automatic control theory are discussed.The reform measures and practical effects of the course of automatic control theory are described,which provide a reference for the teaching of frequency domain series correction.
