摘要： The invention relates to a hydraulic drive device, comprising a piston which is guided displaceably in a cylinder chamber along a working axis and adjoins a working pressure chamber that can be pressurized by hydraulic fluid, and comprising a control means that is guided in the piston at least in some sections between different control states in order to control the flow of the hydraulic fluid from a high pressure supply into the working pressure chamber to move the piston in the working direction and from the working pressure chamber to a return flow chamber, wherein the region of the piston facing away from the working pressure chamber delimits a low pressure chamber that is pressurized by a low pressure supply for hydraulic fluid during the operation of the device such that the piston is moved back against the working direction when the control means connects the working pressure chamber to the return flow chamber. The invention furthermore relates to a method for operating a hydraulic drive device.

摘要： The invention relates to a control device (11) for the position control of a hydraulic cylinder unit (1). Said control device comprises a controller (15) which, on the input side, receives a set position (s*) of a piston (3) of the hydraulic cylinder unit (1) and an actual position (s) of the piston (3) and determines a preliminary manipulated variable (u') for a valve control unit (7) of the hydraulic cylinder unit (1) based on the difference (δs) of the set position (s*) and the actual position (s). A linearization unit (17) is mounted downstream of the controller (15) and multiplies the preliminary manipulated variable (u') with a linearization factor (F) and outputs the preliminary manipulated variable (u') multiplied with the linearization factor (F) as the final manipulated variable (u) to the valve control unit (7) so that the piston (3) is adjusted at an adjustment speed (v). The linearization unit (17) determines the linearization factor (F) dynamically as a function of the actual position (s) of the piston (3) and of working pressures (pA, pB, pP, pT) that prevail at both sides of the piston (3) and at the inlet and outlet side of the valve control unit (7). The linearization factor is determined in such a manner that a ratio of the adjustment speed (v) to the difference (δs) of the set position (s*) and the actual position (s) is independent of the actual position (s) of the piston (3) and the working pressures (pA, pB, pP, pT). In the specific case where the controller (15) is configured as a P controller, the order of the controller (15) and the linearization unit (17) can be reversed.

摘要： When a command to move a ram (5U) is issued, the ram command speed made equal to a constant warmup speed lower than a target speed is commanded until a canceling speed judging unit (75) judges that the speed of the ram (SU) calculated by a ram speed calculating unit (51) reaches a predetermined warmup canceling speed. When the canceling speed judging unit (75) judges that the speed of the ram (5U) exceeds the predetermined warmup canceling speed, the warmup speed is canceled and the ram (5U) is accelerated to the target speed.
