Abstract:
A reactive power control system is provided. The reactive power control system computes a required value for a reactive power based on a state observer method for at least one electrical element in an electrical system. The reactive power control system also generates a reactive power command based on the required value of the reactive power. The reactive power control system further transmits the reactive power command to the electrical element in the electrical system for generating the required value of reactive power to compensate for a voltage change induced by the respective electrical element in the electrical system.
Abstract:
The present invention relates to a method and a device for automatically stacking tires (4) on a support (1). According to the method, geometrical data of the tires (4) and/or a digital model of the tires (4) is provided, based on the geometrical data and/or the tire model and a predefinable size of the support (1), an algorithm calculates a stacking pattern for the tires (4) on the support (1) by taking into account a predefined size of the support, said stacking pattern making it possible to store the largest possible number of tires (4) in a stable manner on the support (1). Positional data of the tires (4) are adopted from the stacking pattern and associated trajectories of a handling device for stacking the tires (4) are generated and stored according to the stacking pattern. The stored positional data and trajectories are retrieved and transferred to the handling device, which receives the tires (4) at a given receiving position and puts the same on the support (1) in accordance with the positional data and associated trajectories. The present method and the associated device make it possible to automatically stack the tires with an optimal stacking pattern for the tires.
Abstract:
A method for localizing an object moving in an unknown environment. The method includes providing k position marks at undetermined positions p1, p2, . . . , pk that are spaced apart from one another, where {p1, . . . , pk}ε, where k is a natural number greater than or equal to 3, and repeatedly measuring the distances between the object and each of the position marks independently of one another at uncontrolled instants, such that distance values {r1, . . . , rn}ε are present at instants {t1, . . . , tn}ε. The method further includes determining a motion curve x(t)ε according to x ( t ) = ∑ i = 1 n α i k ( t , t i ) , where n represents a number of distance measurements used and each function k(t, ti) is a positively defined kernel function, and where {α1, . . . , αn}ε are coefficient vectors that are estimated using smoothness conditions based on a regularization term formed with the kernel functions.
