I was reading an application note on Electro-Hydraulic Control Systems... The author of the note wrote: "In general, applications with bandwidths of greater than 20Hz or control power greater than about 15kW, may be regarded as suitable for Servo Hydraulic Techniques"...
"Hydraulic system are mechanically "stiffer", resulting in higher machine frame resonant frequencies for a given power level"...
My questions are as follows:
1) What is the physical significance or meaning of 'bandwidth' in a Servo Hydraulic System?? I mean, in physical form what "reaction" of the Servo Hydraulic System will reflect bandwidth?? (I assume that a Servo Hydraulic System consists of a servo controller, a FCV, an actuator, a position feedback pot and a hyd power supply... Where is the 'bandwidth' associated in these components?)
2) What is the meaning of the word "stiffer" in the above paragraph??
