Question: You are required to design a pot-pot servo positioning system. Given: Electric supply: 15 VDC Command pot and feedback pot length: 6 in. Servo valve requires 100 mA to open to the full open position Servo valve deadband 5 mA Maximum flow 10 GPM
Cylinder: double rod, 3.25-in. bore, 1.75-in. rod, 6.5-in. stroke Maximum load 3500 lbf Total volume of fluid in lines between the cylinder and servo valve 9.42 in3 Fluid is oil with compressibility E = 5 x 10-6 in2/lbf
Required: Find the amplifier gain that gives a velocity constant equal to ω/3 where ω is the natural frequency of the system.
