P6.7.1** Consider the response of an open-loop underdamped process to a step input change of 500 lb/h shown in Figure P6.7.1. Based on this response, develop a second-order plus deadtime transfer function model for this process. (Hint: Develop the second-order approximation first then determine the deadtime.) T(°C) 6 5
