**Problem 18: Control System Stabilization**

Given the transfer function for the open-loop system:

\[ G[s] = \frac{(s-1)}{(s+1)(s+2)} \]

Select a controller to stabilize the closed-loop system.

Options for controllers:

(a) \[ G_C[s] = \frac{0.167(s-1)}{s} \]

(b) \[ G_C[s] = \frac{0.75(s+1)}{s} \]

(c) \[ G_C[s] = \frac{0.5(s+1)}{s} \]

(d) No such controller exists.

Choose the appropriate controller among the given options to achieve stability in the closed-loop system.

Assume the following block diagram for the entire exam.

The diagram is a block diagram illustrating a control system or signal processing system. Here's a detailed explanation:

1. **Input Signal (R[ω])**: The diagram begins with an input signal denoted as R[ω], which enters a summation node.

2. **Summation Node (Σ)**: The summation node sums the input signal R[ω] with a feedback signal (denoted by the line looping back to the summation point). The result of this summation is an error signal E[ω].

3. **Error Signal (E[ω])**: The error signal E[ω] is then fed into a controller block labeled Gc[ω].

4. **Controller Block (Gc[ω])**: The controller processes the error signal to produce a controlled output.

5. **Controlled Output**: The output from the controller block then goes to another block labeled G[ω].

6. **Block G[ω]**: This block represents a system or plant that processes the input from the controller block to generate the final output signal Y[ω].

7. **Output Signal (Y[ω])**: The final output of the system is Y[ω]. This output is also fed back into the summation node as part of the feedback loop.

**Explanation of Diagram Components:**
- **Feedback Loop**: The path from Y[ω] back to the summation node represents a feedback mechanism, which is essential for adjusting the output in relation to the input.
- **Blocks and Signals**: Each block represents a system function or operation applied to signals that help control or modify the response of the system.

This diagram illustrates the interactions between different components in a closed-loop control system, crucial for tasks requiring precise output regulation.
