ME 41100 - System Dynamics and Control (Fall 2023)

Course Description

This is a fundamental undergraduate course on the classical theory of dyanmic systems and control. It provides an introduction to mathematical modeling, analysis, and control of linear dynamic systems. The course emphasizes the frequency-domain techniques and the state-space methods for the analysis of linear systems and the synthesis of control laws meeting given design specifications. Some familiarity with linear algebra, as well as ordinary differential equations (ODEs), is strongly recommended, although the necessary material will be reviewed in the context of the course.

Textbooks and Reference Materials

The main textbook for the course will be:

  • G. F. Franklin, J. D. Powell, A. Emami-Naeini, Feedback Control of Dynamic Systems, Pearson.

The most up-to-date edition of this book is the 8th edition. Previous editions should, for the most part, be fine, as the material will not be substantially different.

Other optional references for the course's materials are:

  • K. Ogata, System Dynamics, 4th ed., Pearson Prentice Hall.

  • K. Ogata, Modern Control Engineering, 5th ed., Prentice Hall.

  • W. Palm III, System Dynamics, 3rd ed., McGraw-Hill.

  • R. C. Dorf, R. H. Bishop, Modern Control Systems, 13th ed., Pearson.

Grading Policy

Your grade will be assigned roughly according to the following percentages.

  1. Weekly homeworks: 30%

  2. Midterms: 20%

  3. Final exam: 50%

No late homeworks will be accepted. If answers are not accompanied by satisfactory explanations (e.g., all intermediate steps, clearly readable handwriting), no credit will be given.

CCNY Grading System

Exam Policy

The midterm exams will occur during the course's regular time slot. The final exam will occur during the time slot determined by the Registrar.

Exams will be closed book and closed notes. During exams, you will be allowed to use one reference sheet. Reference sheet must be on a Letter-size paper. Both sides may be used, and the reference sheet must be hand-written.

Academic Integrity

All students are subject to the university's academic integrity policies. Academic dishonesty will not be tolerated in any form. I will strongly adhere to the CUNY Policy on Academic Interity, should the need arise. Instances of academic dishonesty include, but are not limited to

  • Copying solutions from other students during homework or during exams.

  • Solutions from previous years: It is forbidden to look at or copy solutions for homework from previous years. There are certain questions that are asked from year to year because they are good questions: doing these questions yourself will assist in your understanding of the course material and will be crucial in your in-class tests.

You are encouraged to work with other students on your assignments, and to help other students complete their assignments, provided that you comply with the following conditions:

  • Honest representation: The material you turn in for course credit must be a fair representation of your work. You are responsible for understanding and being able to explain and duplicate the work you submit.

  • Give help appropriately: When helping someone, it is important not to simply give them a solution, because then they may not understand it fully and will not be able to solve a similar problem next time. It's always important to take the time to help someone think through the problem and develop the solution.
