Unformatted text preview: y(t) at specified times using the transfer function approach, i.e. using deviation variables in the ODE. 3) Given a written description and/or sketch of a simple process and its operating procedures, calculate process variables as functions of time after setting up and solving the appropriate dynamic material and/or energy balances - which may be linear or nonlinear. For example: Be able to solve a "tank problem" using the transfer function approach. Describe any differences between linear and nonlinear model predictions of responses to step changes in input. 4) Given a transfer function model, reverse the normal procedure to obtain an ODE for the deviation output and input variables or for the full version of the variables. 5) Be able to identity type of transfer function model from a process step response curve or datafile and vice versa: solve for y(t) given G(s) and size of step, solve for G(s) given y(t) and size of step. 6) Be able to switch among any of the possible "forms" of G(s). Some examples are: - standard form (coefficient of lowest order in s = 1) - factored form (equivalent to coefficient of highest order in s = 1) - specification of location of poles and zeros along with gain - given values of stan...
