i need help in how to ste the parameters of a electricl circute as Variables in simulink ?

It will be great for someone to help me and explain to me how to set the parameter of an electrical circuit component as variables in Simulink. I did design the example of the Rectifier and OP-Amp example in math work, but I fail to set the parameter as variable for the sensitivity analysis and Mote Carlo simulation. As will what is the mathematical approach the simulation use to do the for the sensitivity analysis and Monte Carlo simulation.

Hello, you type a variable name into the paramter. Then you need to creat that variable in the matlab workspace. This should let you identify as a paraemter in the SDO worfklow.

thanks so much ... it works ... man it's that easy in the end...

Greetings, I would appreciate your assistance... please review the attachment.

What is the easiest way to add sinewaves with pulses (as a lightning effect) to a physical circuit for sensitivity analysis with Monte Carlo simulation to see how it affects the circuit component?

thanks for the advice ... Farhan

Create the signal you want in SImulink by adding pulses and sin waves together, then inject them through a controlled source (probably voltage, but you can also use a current source). There are some basic pieces in the physical signal library so you create the pulses in Simscape as well, but it's easier to do in Simulink.

You may need to add filtering to your s -> ps converter to make this play nice with the solver If the pulses are instantaneous/step changes, passing them though a fast (small time constant) low pass filter can help the simulation converge better.

thanks it works
