状态空间和电路模拟器
据我所知，目前还没有基于状态空间的通用电路模拟器。尽管有某些算法可以找出如何在电路（由图表示）中找到状态空间（唯一？）。有人尝试编写程序来模拟一些基本电路元件吗？

As far as I know there is no state-space based general purpose circuit simulator around. Though there are certain algorithm to figure out how to find state-spaces (unique?) in a circuit (represented by graphs). Has anyone tried writing a program to simulate some basic circuit elements?

一旦导出了电路的状态空间表示，您就可以使用任何合适的 ODE 求解器来运行时域仿真。
更困难的部分是通过 MNA 或树方法从网表推导状态空间方程。

Old post..
Once you have derived the state-space representation of your electrical circuit, you can use any suitable ODE solver to run the time-domain simulation.
The harder part is the derivation of the state-space equations from a netlist via MNA or a tree approach.

沿着这些路线的商业模拟器有 PLECS、PSIM、Simplis、SimPowerSystems 等。Leon
O. Chua 和 Pen-Min Lin 所著的经典著作《电子电路的计算机辅助分析：算法和计算技术》包含基于状态空间的描述。模拟器。我发现这本书足够了
详细介绍如何成功编写具有理想开关的分段线性网络模拟器。
当您主要对非线性网络（半导体、非线性电感器和电容器等）感兴趣时，基于 MNA 的 SPICE 类
方法可能是一个更好的主意。本书还包含
这些基本算法（在无与伦比的深度），但什么也没有

Commercial simulators along these lines are PLECS, PSIM, Simplis, SimPowerSystems etc.
The classic book 'Computer-aided Analysis of Electronic Circuits: Algorithms and Computational Techniques' by Leon O. Chua and Pen-Min Lin contains a description of state-space based simulators. I found the book sufficiently
detailed to successfully write a simulator for piece-wise linear networks with ideal switches.
When you are primarily interested in non-linear networks (semiconductors, nonlinear inductors and capacitors, etc.) an MNA-based SPICE-like
approach is probably a much better idea. The book also contains
these basic algorithms (in unparalleled depth), but has nothing
on device modeling.
