10.450 Process Dynamics, Operations, and Control Spring 2002 Final Exam In approaching the problems, take great care to identify the process, controlled variable, etc. Use the various tools – block diagrams, transfer function equations – to define the problem before embarking on a solution. In your math manipulations, make use of the tabulated information in the text and notes, such as Laplace transform pairs, frequency responses, time-domain responses for standard system elements. Review your calculated numbers for sense. None of the problems should involve outlandish magnitudes, so an uncomfortable number may indicate an error.
