从非线性参数依赖方程生成线性模型的族需要平衡表面的明确的分析表征。在原始系统参数方面这样做通常是不可能的。引入一种替代的参数化,我们提出了一种有效的方法来计算局部线性参数依赖的家庭。虽然是局部的,但这些族可以在任何地方构建,特别是在其他方法失败的分叉点周围。
Generating families of linear models from nonlinear parameter-dependent equations requires explicit analytical characterization of the equilibrium surface. Doing so in terms of the original system parameters is generally not possible. Introducing an alternative parameterization, we propose an efficient method for computing local linear parameter-dependent families. Although local, these families can be constructed anywhere, specifically around bifurcation points where other methods fail.
