Abstract: A method for the precise measuring operating of a micro-mechanical rotation rate sensor, including at least one seismic mass, at least one drive device for driving the seismic mass in the primary mode (q1) and at least three trimming electrode elements which are jointly associated directly or indirectly with the seismic mass. An electric trimming voltage (u1, u2, u3, u4) is set respectively between the trimming electrode elements and the seismic mass. Each of the electric trimming voltages (u1, u2, u3, u4) are adjusted in accordance with a resonance frequency variable (?T, ?T,0), a quadrature variable (?c, ?C,0) and a restoring variable (?S).

Abstract: For steering a vehicle around obstacles, proceeding along a path from a starting position to an end position, the path including linear sub-paths which are defined by an increment ? and a steering angle ?, a method includes: a) determining a maximum steering angle range and a maximum and a minimum increment range; b) determining the present distance eP from the end position, the target angle ?O, and the angle difference e? between the present vehicle angle and the target angle; c) performing an optimization method for ascertaining a sub-path by minimizing the value of a cost function lO assigned to the sub-path; d) determining the new position by adding the ascertained sub-path to the present position; and e) repeating steps (b) through (d) until the end position is reached.

Abstract: A gate signal is generated by summation of multiple signal profiles. The gate signal is applied to a switching device to switch the switching device between an off state and an on state. While the gate signal is applied to the switching device, at least an n-th order derivative of a load signal of the switching device is detected, with n being an integer which is equal to or larger than 2. Depending on the detected n-th order derivative, one or more of the signal profiles are adapted.

Abstract: For an object on a bearing mounting having a magnetic bearing providing a magnetic field generally produced by an electromagnet, the bearing is regulated based on a position of the object relative to the bearing. The position of the object is determined by reference to an estimate of the inductance obtained using a least squares method, in which the electrical resistance of the bearing is taken into account. The resistance is subject to variations, for example due to temperature fluctuations; however, the electrical resistance can be estimated by regulating the inductance error, ?{circumflex over (L)}={circumflex over (L)}2,sLS?{circumflex over (L)}1,sLS down to zero, where the resistance adjustment facility may be a low-pass filter and an integration controller.

Abstract: The invention relates to a regulator device, preferably as a component of a hydraulic circuit, in particular for regulating fluid-bearing units or units that are driven using a fluid, such as adjustable fluid pumps, which respectively co-operate with at least one actuator, which can be controlled by means of at least one governor in accordance with a predefinable guide variable (pd), said governor detecting output variables (?,p1) at least partially via a recirculation line. The fact that at least one recirculation line comprises at least one monitor (estimator), which estimates the output variables (condition x) that are at least in part unknown for the assignable governor, enables the provision of a regulator device, in which the governor comprises a linear or non-linear monitor for estimating the unknown load.
