控制系统的稳定性研究

自动控制系统包括线性控制系统和非线性控制系统（将非线性系统在一定条件下可看作线性控制系统），无论是哪一个控制系统，如果它不稳定，那就不能投入生产，稳定是控制系统的重要性能，也是系统能够正常运行的首要条件。因此首先要判断控制系统是否稳定．本文所采用的控制系统是否稳定的措施，是代数稳定判断法，胡尔维茨稳定判断法和劳斯稳定判断法．

Study on the Stability in Automatic Control

The automatic control system is made up of linear and non -- Cinear control system, if either of them is unstable, it cannot be put into production Therefore, stability is vital to control systems and is the first guarantee of normal operation. This paper uses algebra method, Hurwiz methoel and Rouse motheel to Judge whether the control system used is stuble or not.
