2. Hydraulic drive highlights
Generally speaking, hydraulic servo-control is not an inexpensive solution. It is not, therefore, a solution for systems with mediocre performance and essentially economic criteria. Hydraulic servo systems should be considered when they alone offer the performance you need, or when they deliver it better than competing systems.
The following is a list (not a ranking) of the performances that should be considered as the strong points of hydraulic servoing.
2.1 Dynamic performance
Hydraulic servo-controls are currently the most efficient when power and response speed are required simultaneously. Whether expressed in terms of cut-off frequency, response time or equivalent time constant, the speed of response to an unexpected command is...
