system control dynamics help

I NEED 2 COPIES AS WE ARE TWO STUDENTS , FOR BOTH WE MUST HAVE DIFFERENT MODELS , PROVIDE ALL NECESSARY SIMULINK FILES , DEADLINE IS STRICT WITHIN 26 HRS . NOTE : MAKE TWO SOLUTION FILES AS STUDENT1.ZIP AND STUDENT2..ZIP . I AM ATTACHING TWO EXAMPLES DONE IN CLASS. ONLY TAKE IT IF YOU ARE 100% SURE AND UR CODES BE PERFECT AND SHOULD RUN.

The vast majority of the course has dealt with systems or mechanisms that have only one degree of freedom,
with lumped parameter models being paramount. These simplifications are often due to convenience rather
than necessity. The project for this term will deal with systems with multiple degrees of freedom and non-
linear terms and graphical modeling techniques.
1. Select an example of a real-life dynamic system that has at least two degrees of freedom and at least
one non-linear constraint. Please select an example that has not been discussed in class. Remember
that a degree of freedom can be described as a mass having the ability to move in a single direction.
Examples of two-DOF systems include a mass that is free to move in the X-Y plane or a two-mass
system constrained to vertical motion. Remember also that the non-linear constraint can be as simple
as hard limits on a spring’s travel, or a spring that has a different constant depending on direction of
motion, among many options. If you have concerns about your model not being appropriate (not
meeting requirements, or being too complicated) please see me.

Build a model of your system using Simulink. Make any assumptions or simplifications you deem
necessary, provided the simplified system still meets the 2-DOF and non-linear requirements. Make
educated guesses about parameter values.

3. Compose a document which describes the system, which will cover the following:
A thorough description of your chosen system, including its components and intended
application, as well as what the input and output parameters of interest might be
b. Any simplifications/assumptions you’ve made, if any, and why you believe they are
appropriate
A presentation of your model’s block diagram, identifying the major sections, as well as the
input and output parameters
d. Consider various (or atypical if appropriate) input functions, and investigate their effect on the
output parameters of interest.
e. What implications do the components of your system have on its overall time response? Can
you see any issues that might arise if components are sized inappropriately?
f. Does your system suffer from vibration concerns? If so, how might those concerns be
mitigated?
g. Are there any active control strategies which may be applicable to your system? If so, how
would you propose that such a strategy be implemented?
h. What are the limitations to your model? (ALL models have limitations.) What kinds of
scenarios are not addressed by your model?
Please support any claims with data from your model, with time response or frequency response plots
configured and formatted appropriately.
This assignment is intended as a glorified homework assignment which is intended to address a more realistic
scenario than the typical textbook problem. It is NOT intended to be construed in any way as resembling a
research thesis or capstone project.
