- PLEASE GIVE COMPLETE AND DETAILED SOLUTION The oven shown in Figure 1 has a heating element, qi with capacitances C = 50 J/K. The corresponding temperature is T and ambient temperature is Ta. The thermal resistance of the oven wall is R = 2 K-s/J. The system has a steady-state error in the response, T(t) to a change in the reference input. The steady state error can be reduced if a proportional control action, Kp is included in the controller.
