## Homework Statement:

- (Included in picture below) Essentially, sketching the root locus for a simple control system with negative feedback

## Relevant Equations:

- N/A

From my understanding, the root locus is only concerned with open loop gain. I figured this means you would ignore the negative feedback loop and calculate the root locus from just the plant's function

Workings:

zeros: -1

poles: 0, -2, -2,

relative degree = 2

=> 90-degree asymptotes

meeting point = -3/2

And then sketch using that information

However, in the provided hints:

Looking at this, it seems the open loop transfer function is the two functions (plant and controller) multiplied together

We've never covered this in the lectures, but does this mean that for open loop with negative feedback, you'd just include the negative feedback in the main branch?
