- 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.The unity feedback control system is represented in Figure 3. In order to improve the performance, a PD controller is introduced in the forward path in series with the plant as shown in Figure 4. (i). Evaluate the damping ratio, un-damped natural frequency and percentage overshoot without introducing controller. E = 1070 (ii). Estimate the value of Kd, if the damping ratio to be improved by 25% and thus compare the change in percentage overshoot.Digital Control Systems; Consider the following closed-loop discrete control system depictured in Figure 1.
