Abstract:
Hydraulic drives, systems that use pressurized fluids as transmis-sion medium, have a wide range of applications are widespread in to-day’s industry. Like many other systems, hydraulic drives can get dra-matically improved performance by an appropriately designed feedback controller. Without any automatic control, these systems are often very difficult for a user to operate. Olsberg is a Swedish company specialized in hydraulic drives, pre-dominantly for cranes and other heavy machinery.

Abstract:
The automation of hydraulic mobile machinery, such as excavators, requires high performance control solutions. In hydraulics, this means fast and accurate force, velocity and position control of hydraulic cylinder. Especially the force control is known to be difficult with traditional servo valves. Fast digital hydraulic valves together with modern control solutions can overcome this problem. This paper uses a new force control solution, which is based on the fast digital hydraulic valves and model based control principle. The control solution is applied in a heavy axis mimicking dynamics of m

Abstract:
In the paper a new position signal filtering method with position prediction is presented along with test results using a simulation tool. The complete active heave compensation system performance with input signal filtering is also shown. The control system uses an input acceleration signal taken from the motion reference unit, which usually contains noise that is not acceptable for the position controller. Currently, a Kalman filter is used which is okay to use for certain conditions. The filter works similarly to how it is used for autonomous applications where two input positions are neces
