摘要： A drive system (10), in particular for process automation, includes: a trajectory planning unit (3), which is adapted to provide a trajectory signal (xd) on the basis of a setpoint signal (xs), and an actuator unit (2) having an actuator member (1), in particular a valve member, which actuator unit (2) is adapted to control and/or regulate a position of the actuator member (1) on the basis of the trajectory signal (xd). The trajectory planning unit (3) is adapted to provide the trajectory signal (xd) with a first signal section (s1) and a second signal section (s2), the first signal section (s1) having a straight signal form and the second signal section (s2) having a signal form asymptotic to the setpoint signal (xs).

摘要： A diagnostic method for determining a flap impact of a flap fitting of a process valve, including the steps of: recording a temporal deflection course of a flap of the flap fitting, and detecting a flap impact characteristic in the temporal deflection course.
