### Determining the System Type in Control Theory

To define the type of a given control system, we must examine its components and feedback loop. Let's consider the following system:

#### Controller and System:
\[ C(s) = \frac{K(s + 1)}{s + 0.1} \]
\[ G(s) = \frac{1}{s(s + 3)} \]

where:
- \( C(s) \) represents the transfer function of the controller.
- \( G(s) \) represents the transfer function of the plant (system to be controlled).

### Unit Feedback System:
We assume a unit feedback for the system, meaning the feedback loop has a transfer function of 1.

### Error Coefficients:
For a control system, the position, velocity, and acceleration error coefficients are fundamental in determining the steady-state errors for different types of inputs (step, ramp, and parabolic).

#### Position Error Coefficient (\( K_p \)):
\[ K_p = \lim_{{s \to 0}} G(s) \cdot C(s) \]

#### Velocity Error Coefficient (\( K_v \)):
\[ K_v = \lim_{{s \to 0}} s \cdot G(s) \cdot C(s) \]

#### Acceleration Error Coefficient (\( K_a \)):
\[ K_a = \lim_{{s \to 0}} s^2 \cdot G(s) \cdot C(s) \]

### Steady-State Errors:
The steady-state error for different types of inputs are calculated as follows:

#### For Step Input:
\[ e_{ss} = \frac{1}{1 + K_p} \]

#### For Ramp Input:
\[ e_{ss} = \frac{1}{K_v} \]

#### For Parabolic Input:
\[ e_{ss} = \frac{1}{K_a} \]

### Conclusion:
Determine the system type by calculating these error coefficients and analyze the steady-state error for the given step, ramp, and parabolic inputs. This systematic approach allows us to understand the behavior and accuracy of the control system.
