Research on Teaching Method for Routh Criterion of Automatic Control Theory
Routh criterion is one of the important course contents of the Automatic Control Theory course.However,most textbooks do not present the derivation and proof of the Routh criterion.Meanwhile,in the teaching process,the focus is often put on instilling the use of the Routh criterion rather than explaining its design principle.In order to improve students'understanding of the Routh criterion,based on existing studies on Routh criterion,this article explains the design principle of the Routh criterion,the mechanism for analyzing the system stability,and the processing methods for singular cases,respectively.The goal is to let students have a deeper understanding and easier grasp of the Routh criterion.
