Sensitivity Analysis for a linear model

Hello,

I am trying to understand how certain parameters affect the ouput in the code attached. I want to understand how changing one parameter affects the output while keeping all other parameters fixed.

The output in question is Pi and I want to understand how sensitive it is to parameters like Gi, di, D1, D2, n0.

And I want to plot how Pi varies with each of these inputs. How do I go about this? Do I need to use Simulink for this?

"I am trying to understand how certain parameters affect the ouput in the code attached. I want to understand how changing one parameter affects the output while keeping all other parameters fixed".

I have check the attched code.

Step 1: Varry di and keep all other parameters fixed

plot(di,pi);
hold on;

Step 2: Varry D1 and keep all other parameters fixed

plot(D1,pi);

..do the same for other paprameters........ (with re-assigning the same value to respective parameters)

From the graph pi varriation with parameters, you can estimate the sensitivity of the respective parameters on pi. The most variation of pi signify the most sensitive on respective parameters.

Hope you can do that!
