1- For the
problems below document the design process. Clearly show the final compensator
that you have obtained.
2-If you had to redesign (a compensator) briefly indicate what assumptions you had and the compensator you obtained (omit all other details in your final report).
3-If you were
unable to a satisfactory design a compensator for a given problem after several
trials, follow the step 2 however include your best results with more details
as indicated by step 1.
4- Provide a nice / organized
/ clean report, including matlab script file of your work along with required figures
(simulation, bode plots, etc.). Do not just print out Matlab command window,
error messages, etc.
1- For a unity feedback
control system with plant transfer function of
phase-lag compensator such that the resulting controlled system has a Phase
Margin of at least 45°
most 65° with a static error
constant coefficient in the range of 115 to 130.
Document the design process.
design by determining/showing the explicit form of the compensator, resulting
Phase Margin, Gain Margin of the compensated system, as well as including step
responses of the uncompensated system, gain adjusted system, and
2- Design a phase-lead
compensator for the system given in problem 1 (use the same values of Phase
Margin and error coefficient).
3- Compare and contrast the
resulting compensated systems of problem 1 and 2. Is there any clear reason why
one is a better choice than the other?
4- Design a PID compensator for a unity feedback
system with plant transfer function
Design a PID
compensator that meets the following specifications:
The closed-loop system transfer function has exactly two poles.
The closed loop controlled system has dominant poles with
frequency of 4.5 rad/s and damping ratio greater than
The closed-loop system exhibit zero steady state error due to a unit step
the rational for the design, final compensator transfer function, and step
response of closed-loop compensated system.
