摘要： The present invention relates to a compact motorized rotational stage for microscopy applications and control methods for automated sample orientation/rotation. The rotational stage includes a motor, a rotational motion transmission mechanism, and a rotating sample holder for accommodating a holding device such as glass slides/Petri dishes of different sizes. Mouse embryos are used as an example to explain the control methods. A pattern recognition utility was developed for identifying mouse embryo structures. The transformation between the holding device rotational coordinate frame and the translational positioning stage coordinate frame is calibrated during image-based visual servo control. The polar body of an embryo is oriented through purely image-based visual servo control or through coordinate transformation and closed-loop position control.

The slave computer system (42) includes logic means for receiving data and command input from the master computer (44) in the central control system, processing this information as required, generating a signal capable of operating a variable speed drive (46), and reporting an echo back signal to the master computer (44) indicating that the driven component has reached the desired position. The slave computer (42) also includes logic means for transmitting current position and stored end point and velocity profile information back to the master computer (44) for output to a monitor at the operator's request.

摘要： The invention relates to a positioner, especially for a valve that can be actuated by means of a drive. The inventive positioner comprises a locator (9) for detecting the real position of an actuator (7) and a control unit (13) for comparing the real position with a desired position that can be predetermined and for generating an actuating signal. A magnet (18) having a magnetoresistive sensor, preferably a GMR sensor, is provided as the locator. The locator (9) is less easily soiled and is less prone to wear and tear than a conventional slider potentiometer. The positioner is thus less interference-prone.

摘要： The invention relates to a control device (11) for the position control of a hydraulic cylinder unit (1). Said control device comprises a controller (15) which, on the input side, receives a set position (s*) of a piston (3) of the hydraulic cylinder unit (1) and an actual position (s) of the piston (3) and determines a preliminary manipulated variable (u') for a valve control unit (7) of the hydraulic cylinder unit (1) based on the difference (δs) of the set position (s*) and the actual position (s). A linearization unit (17) is mounted downstream of the controller (15) and multiplies the preliminary manipulated variable (u') with a linearization factor (F) and outputs the preliminary manipulated variable (u') multiplied with the linearization factor (F) as the final manipulated variable (u) to the valve control unit (7) so that the piston (3) is adjusted at an adjustment speed (v). The linearization unit (17) determines the linearization factor (F) dynamically as a function of the actual position (s) of the piston (3) and of working pressures (pA, pB, pP, pT) that prevail at both sides of the piston (3) and at the inlet and outlet side of the valve control unit (7). The linearization factor is determined in such a manner that a ratio of the adjustment speed (v) to the difference (δs) of the set position (s*) and the actual position (s) is independent of the actual position (s) of the piston (3) and the working pressures (pA, pB, pP, pT). In the specific case where the controller (15) is configured as a P controller, the order of the controller (15) and the linearization unit (17) can be reversed.

摘要： Kinematic control of an electronic positioner and its associated actuator is effected through a control algorithm that delivers energy to the actuator based on observed motion produced by a previous delivery of energy. The algorithm achieves control based on a desired or user-specified resolution. Electronic braking between energy delivery intervals improves the speed at which the desired position is achieved. Temperature of the force producing mechanism is determined, as by monitoring energy consumed, and used to control how power is delivered to the actuator.
