Abstract: A method for controlling a part movable with a coil. In this case, a current flowing through the coil and/or a voltage applied to the coil is/are scanned in order to generate a coil signal. In a further step, at least one movement parameter representing an oscillatory movement of the part is ascertained by using the coil signal. Finally, at least one signal parameter of a dither signal is optionally changed to generate the oscillatory movement by comparing the movement parameter to the at least one setpoint value to adapt the oscillatory movement to the setpoint value.

Abstract: A method for testing a technical system. Tests are carried out with the aid of a simulation of the system. The tests are evaluated with respect to a fulfillment measure of a quantitative requirement on the system and different error measures of the simulation. On the basis of the fulfillment measure and each of the error measures, a classification of the tests is carried out as either reliable or unreliable case by case. A selection among the error measures is made on the basis of a number of the tests classified as reliable.

Abstract: A method for assessing a control loop. In the method, the control loop is assigned one degree of fulfillment each with respect to at least three quality criteria. The surface area of a polygon having a geometry defined by the degrees of fulfillment is determined. An overall control quality of the control loop is evaluated on the basis of the surface area.

Abstract: A method for operating an axial piston machine of swashplate design, in which a swashplate is settable by means of an adjustment device, and in which a controlled variable of the axial piston machine is regulated by predetermining a manipulated variable. Under the assumption of a constant intended value of the controlled variable, a future profile of the controlled variable is ascertained using a model of the axial piston machine in which respective current values of at least one operating variable of the axial piston machine, which comprises the controlled variable, and a current value of the manipulated variable are taken into account. A value to be set for the manipulated variable is ascertained and set taking into account the future profile of the controlled variable.

Abstract: A method for controlling a hydrostatic drive, which has a driving engine, a hydraulic pump coupled to the driving engine and a hydraulic motor coupled to the hydraulic pump by way of a pressurized hydraulic work line, includes calculating a manipulated variable vector comprising at least one manipulated variable for the hydrostatic drive based on (i) an output torque setpoint value for a torque on a secondary shaft driven by the hydraulic motor, (ii) a rotational speed and torque of the driving engine emerging from a predetermined operating point characteristic for the driving engine, and (iii) volumetric and mechanical losses of at least one adjuster unit comprising the hydraulic pump and the hydraulic motor. The manipulated variable vector is used to control the hydrostatic drive.

Abstract: A couch top includes a top, a base, a universal joint coupling the top and the base, and actuators mounted on the base to pitch and roll the top. Feedback devices may be fitted on the rotating ends of the universal joint to provide feedback for a control loop. Each actuator has an actuated end that translates vertically to lift or lower the top. The vertical movement may be derived from a carriage riding in place on a translating inclined plane. When the actuated ends move in the same direction, they pitch the top. When the actuated ends move in the opposite directions, they roll the top. Feedback devices may be fitted on motors in the actuators to provide feedback for the control loop.
