Reconsider Example 10.9. Build Simulink block diagrams to simulate open and closed-loop control with parameter variations. Verify the steady-state response values \(y_{\mathrm{ss}}\) obtained in Example 10.9.

Example 10.9:

Consider a plant whose transfer function is \[G(s)=\frac{4}{s+10}\]

a. Build a Simulink block diagram associated with Figure 10.18 to simulate openloop control with disturbance input. Assume that the controller is \(K=2.5\), the disturbance is a constant of -1 , and the reference is a unit-step function with the step time at \(t=0 \mathrm{~s}\). Compare the steady-state values of the responses without and with the disturbance.

b. Build a Simulink block diagram associated with Figure 10.19 to simulate closed-loop control with disturbance input. Assume that the controller is \(K=50\). The disturbance and the reference are the same as those in Part (a). Compare the steady-state values of the responses without and with the disturbance.
