Underactuated multibody systems possess more degrees of freedom than independent control inputs. The inverse model can be used as a feedforward controller in a two degree of freedom control structure. Servo-constraints constrain the output to a specified trajectory and happend the equations of motion to form a set of differential-algebraic equations (DAEs). The resulting DAEs might be of higher differentiation index and are thus difficult to solve numerically. Here, different solution and analysis methods for the servo-constraints approach are compared. Especially, various solvers are analyzed with respect to real-time capability and accuracy.enhttp://rightsstatements.org/vocab/InC/1.0/TechnikConference Proceedings10.15480/882.4290http://imsd2018.tecnico.ulisboa.pt/Web_Abstracts_IMSD2018/pdf/WEB_PAPERS/IMSD2018_Full_Paper_25.pdf10.15480/882.4290Journal Issue
