A closed-loop control system on an air con unit is created using a proportional controller. (Image added for reference) Show that such a system has a steady state error of 1/(1+Kp) and therefore the steady state error condition can be achieved with a proportional gain of 9 or more.
I have been given the task as a tranee control engineer to design a closed-loop controller an air conditioning unit so that it has the following properties: Maximum overshoot: 10% , maximum time to reach 99% of steady state: 10 seconds, Maximum steady-state error: 10% i have to design a PD controller in a closed-loop system - The steady state error is 1/(1+KP) so i need KP to be at least 9 to meet the brief. I need to choose the K’D parameter so that the zero that it produces is placed somewhere between the open-loop pole, therefore put it at s = -1. I've to assume the closed loop transfer function for this system fits the standard form of a second order response when performing calculations of natural frequency, damping ratio and gain and for plotting the unit step response. I have added the example diagram of a closed-loop system with PD control i was supplied.

Consider a home heating system consisting of a natural gas-fired furnace and a ther- mostat. In this case the process consists of the interior space to be heated. The ther- mostat contains both the measuring element and the controller. The furnace is either on (heating) or off. Draw a schematic diagram for this control system. On your diagram, identify the process outputs and all inputs, including disturbance variables.
