(Solution) - Proportional control action applied to the flow rate qmi can -(2025 Original AI-Free Solution)
Paper Details
Proportional control action applied to the flow rate qmi can be used to control the liquid height, as shown in Figure P11.19. Consider the specific plant
Gp (s) = H2(s) / Qmi (s) = 5 (s + 4) / (s + 3) (s + p)
The proportional gain is Kp = 2. The likely value of p is p = 7, but it is known that p might be greater than 7. Use the root locus plot to investigate the roots of the system for p ? 7.
