Design an electric circuit with at least three storing elements and one resistance. The circuit must contain at least three state variables. The input can be DC voltage source or DC current source. All the initial conditions can be zero for the project.

c) Obtain your output waveform in MATLAB/SIMULINK by using schematic, state space matrices, and block diagram.

e) Find your output step response after t > 0 in MATLAB/SIMULINK . You can use inverse Laplace feature of MATLAB/SIMULINK .

g) If when t = 1 sec, input source value is increased 20%, obtain the output waveform of the circuit by using MATLAB/SIMULINK .

i) Examine the same system (in part a) with AC source in MATLAB/SIMULINK .

j) Determine design requirements of your DC system and test your system step response. If needs, adjust your system step response by using Control System Designer in MATLAB/SIMULINK .
