At time = 0, a constant heating power of 100 kW is applied to a boiler that intends to raise the temperature of the fluid inside to 100 ºC. The initial temperature of the fluid is 25 ºC. Temperature is taken every 2 minutes, starting at t = 0. The log after 1 hour is shown below. The x-axis is time (in minutes) while the y-axis is the temperature T. The system may be assumed to be of first order. Let θ(t) be the function describing the temperature increase, i.e. θ(t) = T(t) - 25, where T is the actual temperature. The input power is p(t) = 100 u(t) kW. 1. What is a feasible time delay, in minutes, for the system? 2. What is the DC gain of the system O(s)/P(s) in Cº/kW? 3. What is the transfer function O(s)/P(s)
