Textbook:

  1. R. Dorf and R. Bishop, Modern Control Systems, Pearson.

Engineering Design Statement:

This course focuses on design in the laboratory and in the homework. The problems are relatively unspecified and the student is challenged to complete the problem specifications, propose a design strategy and complete the iterative steps required to select the “best” set of parameters. The student is required to continually use computer-aided design software and for two systems to actually verify the results of the desing using a constructed system with actual components.

Relationship to Outcomes:

Students who have successfully completed this course should have achieved:
