Question: Figure P11.24 shows an electro hydraulic position control system whose plant transfer function for a specific system is Gp (s) = Y (s) / F

Figure P11.24 shows an electro hydraulic position control system whose plant transfer function for a specific system is
Gp (s) = Y (s) / F (s) = 5 / 2s3 + 10s2 + 2s + 4
a. Use the ultimate cycle method to design P, PI, and PID controllers.
