Frequency Stability Criteria of Multivariable Nonlinear Control System

基于广义频率响应函数矩阵，讨论了多变量非线性系统的稳定性问题．文中得到了多项式类多变量非线性系统的稳定性判据，它与李雅普诺夫方法相比在工程上更容易使用．最后通过仿真实例对结论进行了验证．

The stability of multivariable nonlinear control system is discussed in connection with the generalized frequency response function matrix. The frequency stability criteria are proposed for the polynomial class of MIMO nonlinear control system. It is more useful in practice than Lyapunov method. Finally, simulation example is given to verify the results.
