Though proportional control gets the nod in more applications (33%) than servo control (22%), neither one is dominant say many engineers (45%). That's according to a recent survey of Design News readers by Reed Research Group. That could change, as more vendor companies, including Festo, Parker Hannifin, and HR Textron focus on developing new and better servo technologies for fluid power apps. Major reason for the niche to grow? Lower cost. In fact, two thirds of engineers say that if they could obtain servo control for the price of proportional control, they'd do it.
