Question: Design a pot-pot positioning system using the following information:

Load: a. Maximum mass to be moved: 16 lbf·s2/in.

b. Volume of fluid under compression:

Cylinder + Lines = Total

24.6 + 9.4 = 34 in³

Cylinder: a. Maximum cylinder speed: 2 in/s

b. Cylinder area: 4.91/in²

Servo valve: The valve opens completely with 6-mA input. Assume that a valve is selected to give the maximum flow to the cylinder at full open.

Potentiometers: a. Length of command pot and feedback pot: 8 in.

b. Power supply voltage: 15 VDC

Required: a. Find the maximum amplifier gain for stable operation.

Hint: Use the "rule of thumb" that the velocity constant shuld not be greater than one-third the natural frequency. If the valve deadband is 1% of rated current, find the position error for this system.
