摘要： The invention relates to a coil system for the contactless magnetic navigation of a magnetic body (1) in a work space, wherein the coil system comprises a plurality of coils and a current controller for controlling the respective currents in the plurality of coils. In order to navigate the magnetic body (1) to a variably predeterminable position (P) in the work space, the current controller is designed such that the currents in the plurality of coils are such that the magnetic forces (F

4 ) at the edge of a convex environment (Ω) around the predetermined position (P) are directed into the environment (Ω). The coil system according to the invention has the advantage that a movement of the magnetic body toward a spatial position is achieved without any mechanical movement of the coil system and without a positioning system for determining the position of the magnetic body. The coil system is utilized particularly in a medical device, wherein a magnetic body in the form of a probe is moved in the body of a patient. In this way, fast navigation of the probe in the patient’s body can be achieved without mechanical movements of the patient table or of the coil system.-

摘要： The invention relates to a plant (1) of the primary industry, having a number of plant components (2). A target value optimizer (4) of a control system (3) of the plant (1) determines threshold values (X*) for the individual plant components (2) based on predetermined target variables (Z) utilizing an optimizer-internal model (5) of the plant (1). The target value optimizer (4) supplies the respective target values (X*) to a model-based controller (8) of the control system (3) controlling the respective plant component (2), at least for part of the plant components (2). The respective model-based controllers (8) receive current values (X) at least from the respective plant component (2). They determine controlled variables (Y) for the respective plant component (2) based on the target values (X*) fed to them, and based on actual values (X) received by them, utilizing a controller-internal model (9) of the plant component (2) regulated by them, and output the controlled variables (Y) determined by them to the respective plant component (2). A model identifier (11) associated with the respective model-based controller (8) receives the controlled variables (Y) output to the respective plant component (2) by the respective model-based controller (8) and the actual values (X) fed to the respective model-based controller (8), determines parameters (P) based on the controlled variables (Y) and actual values (X) received, and optimizes the controller-internal model (9) of the respective plant component (2) based on the parameters (P). The target value optimizer (4) receives the parameters (P) determined by the model identifiers (11) from the same, and optimizes the optimizer-internal model (5) of the plant (1) utilizing the parameters (P).
