Unformatted text preview: UNIVERSITY OF CALIFORNIA AT BERKELEY Department of Mechanical Engineering ME132 Dynamic Systems and Feedback Fall 2009 Homework #1 Due: Friday, September 4 Announcements: All homework will be due at 5:00 pm on the due date, in the drop box labeled ME 132 on the third floor of Etcheverry Hall. 1. Dynamical systems with feedback exist in many fields of study. Provide an example of a feedback system in each of the following areas: (a) Any engineering discipline (b) Biology (c) Economics (d) Politics For each example, identify the controller, actuator(s), plant, sensor(s), output, dis- turbance(s), and noise. Draw a block diagram showing the interconnections between controller, actuator, plant, and sensor, and label the signals for the output, disturbance, and noise. Example: An example of a biological system with feedback is the regulation of blood glucose concentrations in human beings. It is desired that the concentration of blood glucose remain nearly constant because some components of the nervous system (such as the...
