Nowadays, fractional order differential operators, as a generalization for classical differential operators, have established their key-role in modeling, analysis, and implementation of specific circuits and systems in which one typically faces nonlinear behaviors. It enforces to exploit analysis and implementation methods covering simultaneously “fractionality” and “nonlinearity” aspects. This special section, entitled “Nonlinear Fractional Order Circuits and Systems: Advanced Analysis and Effective Implementation,” aims at introducing some of these methods.

客座社论非线性分数阶电路和系统特别部分的介绍：高级分析和有效实现

如今，作为经典微分算子的概括，分数阶微分算子已经建立了它们在特定电路和系统的建模，分析和实现中的关键作用，在这些电路和系统中，典型的非线性行为通常会发生。它强制利用同时涵盖“分数”和“非线性”方面的分析和实现方法。这个标题为“非线性分数阶电路和系统：高级分析和有效实现”的特殊部分旨在介绍其中一些方法。
