### Transcription:

**Problem 5:**
Sketch the positive root locus for the system shown below. Determine the required value of \( K \) so that the control system has critically damped poles. Find the pole locations using this value of \( K \). Estimate the rise time and the steady-state error with a unit-step reference input using this value of \( K \). ~~Use Matlab to plot the unit-step response using this value of \( K \).~~

#### System Diagram:
The system block diagram consists of the following components:

1. **Summation Block (\(\Sigma\)):**
   - Inputs: \( R \) (Reference) as the positive input and feedback as the negative input.

2. **Gain Block:**
   - Denoted by \( K \).

3. **Transfer Function Block:**
   - Transfer Function: \( \frac{s + 4}{s^2 + 3s + 2} \).
   - Output: \( Y \).

The system is a closed-loop feedback control system, where the output \( Y \) is fed back into the summation block to compare against the reference input \( R \).

Expert Solution
Step 1

Given the block diagram:

Electrical Engineering homework question answer, step 1, image 1

We need to sketch the root locus for the system.

We need to determine the required value of K so that the control system has critically damped poles, we need to find the pole locations using this value of K.

We need to estimate the rise time and the steady-state error with a unit reference input using this value of K.
