Specialized Power Systems
一般需要powergui block或solver configuration；
使用sum block叠加多个信号，如给输入加特定频率谐波；
use the Controlled Voltage Source block to inject a voltage in an electrical circuit;
电压源和电容不能直接串联，应串入小电阻；电流源和电感不能直接并联，并入大电阻。
measure the impedance versus frequency
命令画伯德图如何控制对数坐标还是普通坐标？？AC Current Source注入小信号幅值为什么是0？这个文档写的很差。
freq=0:5000;
w=2*pi*freq;
bode(sys1(1,2),w);
powergui中可以设置仿真变量初值，为0、稳态或任意给定值。
About Electrical Modeling and Simulation
You can connect Specialized Power Systems blocks to Simulink blocks either:
1. Directly, through Simulink signal input and output ports;
2. Through measurement blocks from the Measurements sublibrary of the Fundamental Blocks library. 如ssc_new_elec中包含的controlled voltage source和voltage sensor;
3. use blocks from the Simscape > Electrical > Specialized Power Systems > Fundamental Blocks > Interface Elements library to interface between them;
4. 如ssc_new中展示的，使用PS-Simulink Converter和Simulink-PS Converter进行信号转换。

solver
de23t and ode15s, are recommended for most applications because they run faster and work better for systems with a range of both fast and slow dynamics. The ode23t solver is closest to the solver that SPICE traditionally uses；
To use Simulink® Coder™ software to generate standalone C or C++ code from your model, you must use the ode14x or ode1be solvers. For more information about code generation, see Code Generation (Simscape).
errors
为开关增加电阻和结电容来避免不稳定震荡。example：>> Astable Oscillator ；
Read Troubleshooting Simulation Errors (Simscape) to learn about general troubleshooting techniques.
注意不要丢失参考信号，如Ground，see Grounding Rules.
