BE 4815 - Biomedical Feedback Control Systems

3 lecture hours 2 lab hours 4 credits


Course Description
The objective of this course is to expand topics in classical feedback control theory, introduce modern control theory, and to apply these topics to the solution of classicall feedback control problems in biomedical engineering related areas. The student will expand their abilities to analyze control systems using Routh-Hurwitz, root-locus, and frequency response analysis. The students will use those techniques for P, PI and PID feedback control system design. Topics related to the design of control systems in state space will also be introduced. MATLAB and Simulink will be used model control systems. In the laboratory, the student will design and implement both in software and in hardware the temperature control of an incubator. (prereq: BE 4805 )
Course Learning Outcomes
