** Exercise 1: **Plot (1) the block diagram of this example, (2) results from two scopes, (3) results from workspace using standard MATLAB commands

** Exercise 2: **Use

**Time**block,

**Transfer Fcn**block, a

**Sum**block,

**Scope**, and

**To Workspace**block to create a Simulink model of this closed loop system. Choose proper stop time for the simulation.

(1) Plot the block diagram of the system.

(2) Show the step response of the system (Output y) from both scope and workspace

** Exercise 3: **Add two more second order closed-loop systems (withand) in the same Simulink file. Put three outputs y, y1, and y2 together in one scope. 0.4 = 1.2 =

(1) Plot the block diagram of the simulation file.

(2) Plot the outputs from both scope and workspace

** Exercise 4: **Consider the feedback system shown in the figure below.

** Exercise 5: **Consider the feedback system shown in the figure below. The variables ‘K’, ‘a’ and ‘b’ are k=10.8e8, a=1, b=8 and J=10.8e8
