Designing a PID Controller
24118 Designing a PID Controller For the process, P = 1/(s + 1)(s + 2), design a PI controller, G = (k_p)(s + 1/T_i)/s, to have a closed loop dominant pole pair with w_n = 1.3 and delta = 0.5. Design T_i and then k_p using root locus methods.

Control Systems Comparison
For the proportional controller, sketch the root locus using MATLAB with 0 < K < ∞. Determine the range of K which results in stability. Determine the value of K, K/s, and K(1+1/s) so that the design specifications are satisfied

PI Controller and Nyquist Analysis
It has
a transfer function,
, kp is the proportional gain, Ti is the "reset time"
For an integrating process, P(s) = 2/s, investigate the positive root locus for
a) fixed Ti = 10 and varying kp.
b) fixed kp = 10 and varying Ti.

Design a series controller
Figure 1
The matlab codes for drawing this figure is given as the following:
Kp=100;
Kd=4.9;
Gc=tf([100*Kd 100*Kp],[1 10+100*Kd 100*Kp]);
step(Gc,0.1);
There are some other ways to design the controller such as roots locus, but the direct

Control Systems: Root-Locus Problems
509340 Control Systems: Root-Locus Problems Question 1:
a) Construct the root-locus for the K > 0 for the transfer function
GH = K / [s(s+1)(s^2+7s+12)
b) If the design value for the gain is K = 6, calculate the gain margin.

Design of a PD controller for a double integrator system
Fig. 1 Root locus of the resulting open loop system
A careful choice of Kc and Tc can ensure stability. Note that you have to place the zero of the compensator over the unstable integrator pole (means Tc = 1).
