Open loop transfer function G (s) = ((p + 5)) / ((s + 2) (s + 6) (s + 1)) To draw the curve of the closed loop transfer function of the unit feedback system given as a)Find the real axis cut-off points and angles of the asymptotes. b)Find the imaginary axis breakpoints of the Kkyer curve. c)Find the point of departure of the Kkyer curve from the real axis. d)Draw the root curve. e)When the system is controlled with P control, select the appropriate value of the K gain and calculate the steady-state error ( = 0.45). f)Draw approximately the system output for step inlet. g)Design the PD control system to reduce the rise time by 1/2 compared to the proportional controller. h)Design the PID control system that will reset the steady state error. Note: Calculate all the stages of the PID control structure requested above and draw the relevant graphics on the paper. Design the control structures by writing the relevant codes in the Matlab environment.
