MARKING CRITERIA
[80‐100]: In addition to [70‐79], additional marks will be awarded to the quality of explanations of the
controller design progress and performance analysis. For example, explanation of changing
controller parameters and principle of the controller chosen.
[70‐79]: All MATLAB programs and results are correct. Details of the controller design are provided
and good analysis of the controller performance.
[60‐69]: The MATLAB programs and results related to majority of tasks are correct and correct. Details
of the controller design progress are provided.
[50‐59]: The MATLAB programs and results related to over half of tasks are correct.
[40‐49]: The MATLAB programs and results related to 1/3 of tasks are correct.
[30‐39]: The programs fail to execute and the presented results are incorrect. However, some good
efforts have been made to complete all tasks. Some progress is presented.
[0‐29]: Suitable marks will be given based on the answers produced and the effort made.
DC motor controller design
Consider a DC motor with following parameters:
= . ∗
/
= .
= .
= .
= . /
= . /
Consider the rotation speed is the output of the DC motor.
P1. Please provide transfer function and state space model of a DC motor and plot block diagram. The
input to the system is the applied voltage. The output of the system is the rotation speed of the
motor. (10%)
P2. In MATLAB, plot the step response of the provided DC motor, using both the transfer function and
state space model. Please provide MATLAB code or a Simulink model. (10%)
P3. In MATLAB, please design a P, PI and PID controller of the provided DC motor. Please compare the
results of different controller and different parameters used of the controller, i.e. compare rising
time, settling time, steady state error, overshoot, etc. Please provide MATLAB code or a Simulink
model. (40%)
P4. Please design a state feedback controller of the provided DC motor. Please provide the design
progress, and the step response of the designed controller. Please analysis the step response of the
designed controller. (40%)
