Summary

In this module we have developed the dynamic modeling equations for a perfectly mixed stirred tank heater. We solved for the steady-state conditions, linearized to obtain the state space model, and found the transfer function model. We compared the step responses of the linear and nonlinear models. We also showed the importance of the ``direction'' of initial conditions. Perturbations in certain directions cause a fast response, while perturbations in other directions yield a slow response.
