工程师或科学家关心的数学描述的物理系统不断面临着非线性公式。非线性可以以表示过程或系统动态的微分方程的形式表示。另一方面，可能出现数学描述为代数的非线性控制元件特性，例如滞后、饱和、间隙或非线性阻尼。在许多情况下，系统描述的数学公式可能变得如此笨拙，以至于分析解决方案要么不切实际，要么不可能。尤其是在这样的情况下，数字仿真已经成为一种非常宝贵的工具。
The engineer or scientist concerned with the mathematical description of physical systems is continually faced with nonlinear formulations. The nonlinearity may be represented in the form of a differential equation representing process or system dynamics. On the other hand, nonlinear control element characteristics such as hysteresis, saturation, backlash, or nonlinear damping, whose mathematical description is algebraic, may appear. In many instances the mathematical formulation for system description may become so unwieldy that an analytical solution is either impractical or impossible. It is particularly in situations like these that digital simulation has become an invaluable tool.
