Other policies

Teamwork, collaboration, and helping each other:

For tasks intended for group work, you are expected to find a partner and share the tasks among the group members. In a group project, effective teamwork is critical to maximize the productivity of the whole group. In the submitted work, identify components and indicate percentage contribution by each member to each component.

For tasks not intended for group work, individual submission is required. In this case, you are encouraged to discuss among your friends on how to attack problems. However, you should write your own solution. Copying other people’s work is strictly prohibited.

Academic dishonesty:

Cheating is a very serious offense. It will be dealt with in the most severe manner allowable under University regulations. If caught cheating, you can expect a failing grade and initiation of a cheating case in the University system.

Basically, it’s an insult to the instructor, the department and major program, and most importantly, to the person doing the cheating. Just don't.

If in doubt about what might constitute cheating, send an e-mail to your instructor describing the situation. If you notice anyone cheating, please report it to the instructor or the TA. Do not deal with it yourself.

Discrimination:

State and Federal laws as well as Iowa State University policies prohibit any form of discrimination on the basis of race, color, age, religion, national origin, sexual orientation, gender identity, sex, marital status, disability, or status as a U.S. veteran. Language or gestures of discriminatory nature will not be tolerated. Severe cases will be reported to appropriate offices. See ISU policies at http://www.hrs.iastate.edu/hrs/files/reaffirmation.pdf

Let us make every effort to work together and create a positive, collegial, caring, and all-supportive learning environment in our classroom, laboratory, TA office, and instructor office.

Disability accommodation:

Individuals with physical or mental impairments who are otherwise qualified to perform their work or pursue their studies may request reasonable accommodations to enable them to work or continue their studies.

If you believe you have learning disability, you must contact Student Disability Resources at the Academic Success Center to initiate the accommodation process.

Accommodation for religion based conflicts:

Iowa State University welcomes diversity of religious beliefs and practices, recognizing the contributions differing experiences and viewpoints can bring to the community. Students with religion based conflict should talk to the instructor and appropriate university offices to request accommodations at the earliest possible time.

Student behavior expectations

· Full attendance expected. Notify instructor ahead of time if you cannot attend.

· On-time arrival. Late arrival is a disturbance to the whole class.

· No late HW. Make sure your partner turns in your HW on time if you are to be absent for some reason. Your lowest HW score will be dropped.

· No make-up quizzes. Your lowest three quiz scores will be dropped.

· No make-up exams, except for unforeseeable emergency that is well documented.

· Active participation

o Ask questions

o Answer questions instructor or students

· Be cordial and considerate to other students and TA

· Help each other

· Promptly report/share problems/issues

Prohibited behaviors

· Any foul language or gesture

· Comments to other students that are discriminatory in any form

· Any harassments as defined by the university

· Academic dishonesty

· No alcohol, drugs, or any other illegal / improper substances

OBJECTIVES:

On completion of EE 475, the student will be able to do the following either by hand or with the help of computation tools such as Matlab:

1. Define the basic terminologies used in controls systems

2. Explain advantages and drawbacks of open-loop and closed loop control systems

3. Obtain models of simple dynamic systems in ordinary differential equation, transfer function, state space, or block diagram form

4. Obtain overall transfer function of a system using either block diagram algebra, or signal flow graphs, or Matlab tools.

5. Compute and present in graphical form the output response of control systems to typical test input signals

6. Explain the relationship between system output response and transfer function characteristics or pole/zero locations

7. Determine the stability of a closed-loop control systems using the Routh-Hurwitz criteria

8. Analyze the closed loop stability and performance of control systems based on open-loop transfer functions using the Root Locus technique

9. Design PID or lead-lag compensator to improve the closed loop system stability and performance using the Root Locus technique

10. Analyze the closed loop stability and performance of control systems based on open-loop transfer functions using the frequency response techniques

11. Design PID or lead-lag compensator to improve the closed loop system stability and performance using the frequency response techniques

Topics Covered:

1. Review of signal systems concepts and techniques as applied to control system

2. Block diagrams and signal flow graphs

3. Modeling of control systems using ode, block diagrams, and transfer functions

4. Modeling and analysis of control systems using state space methods

5. Analysis of dynamic response of control systems, including transient response, steady state response, and tracking performance.

6. Closed-loop stability analysis using the Routh-Hurwitz criteria

7. Stability and performance analysis using the Root Locus techniques

8. Control system design using the Root Locus techniques

9. Stability and performance analysis using the frequency response techniques

10. Control system design using the frequency response techniques

11. If there is time, Control system design using the state space techniques

Professional Component:

This course contributes to the professional component of the Electrical Engineering program by enabling students to begin serious studies in automatic control systems, applying the principles learned in mathematics and preceding electrical engineering courses to the understanding, analysis, and design of control systems. The course also contributes to a strengthened foundation for further study, application, and research or development in control systems.
