Popis: The inverse dynamic simulation allows a designer to test the dynamic performance of a closed loop controlled drive without the need to parametrize a feedback controller. Equation based object oriented modeling languages such as Modelica are suitable to build models that can be simulated both, in a forward or inverse fashion. The same model can be used to simulate either in forward fashion or inversely, depending purely on which boundary conditions are specified. To evaluate the usefulness and limitations of the inverse simulation approach for the sizing of a hydraulic servo drive, an open source Modelica library OpenHydraulics is modified to enable inverse simulation. The library is then used for a case study about the sizing of a valve/cylinder hydraulic servo-drive. The inverse simulation supports an intuitive, iterative design approach towards the sizing problem of closed loop controlled drives, such as hydraulic or electric servo drives. The designer can change the size of system components and at any...
