摘　　要：Hurwitz稳定判据是经典控制理论中判定系统稳定性的代数判据。Nyquist判据是频域中判断系统稳定性的判据。给出经典控制理论中线性系统稳定性的另外一种表达形式,并说明Nyquist判据和Hurwitz判据之间的联系。Hurwitz stability criteron is a algebraic stability criteron that is used to investigating the stability of a linear system in classical control theory. The stability of a linear system can be determined in the frequency domain by utilizing Nyquist stability criterion. In the paper, another form based on Nyquist stability criterion is given,and the internal relations between the two criterion is illustrated.

关 键 词：系统稳定性 Hurwitz稳定判据 Nyquist稳定判据
