Abstract: A method for tuning flatness control for rolling a strip in a mill including rolls controllable by means of a plurality of actuators, which mill is modeled by means of a mill matrix. The method includes: a) obtaining an equivalent movement range for each actuator, b) determining a scaled mill matrix by scaling the mill matrix based on the equivalent movement ranges, and c) obtaining a singular value decomposition of the scaled mill matrix for providing flatness control of the strip by means of the actuators. A computer program and a control system for carrying out the above method are also presented herein.

Abstract: A circuit breaking arrangement is disclosed, which is adapted to be coupled to a transmission line arranged to carry direct current for controllably effecting discontinuation of flow of direct current in the transmission line. The circuit breaking arrangement includes a current interrupter unit, which is adapted to, when actuated, interrupt current in the transmission line, and at least one resonance circuit. The resonance circuit is connected in parallel with the current interrupter unit and includes at least one capacitor, at least one inductor and at least one switch element. The resonance circuit is adapted to, upon actuation of the current interrupter unit, generate a resonance current superposing current of any arc generated in the current interrupter unit after actuation thereof, upon closing of the switch element by means of successive discharging and charging of the at least one capacitor. An auxiliary power supply unit is coupled to the resonance circuit and adapted to selectively and controllably convey power to the at least one capacitor, thereby charging it. On a condition that voltage of the transmission line and/or voltage of the at least one capacitor does not comply with a selected voltage criterion, the auxiliary power supply unit is caused to convey power to the at least one capacitor. The circuit breaking arrangement may be arranged so as to allow for conveyance of power transmitted in the transmission line to the at least one capacitor, thereby charging it.

Abstract: A control system for an electric three-phase variable speed motor includes an inverter for providing power to the motor and a control arrangement for controlling the inverter. The control arrangement includes a d and q axis currents determining module configured to repeatedly determine d and q axis currents based on detected currents of the motor. An MTPA control block repeatedly generates reference d and q axis currents based on the determined d and q axis currents and a ratio value such that the ratio of the reference d and q axis currents is equal to the ratio value, which is set to unity. A switching signal generation module repeatedly generates switching signals to control the inverter based on the reference d and q axis currents. A fine adjustment module calculates a magnitude of a current or power of the motor and determines an optimum compensation ratio value.

Abstract: For controlling a robot in a safe way, a highest voltage required for a desired robot movement is calculated. A voltage level in a DC-bus is set on the basis of the highest voltage, and current is supplied to a motor at a robot axis from the DC-bus. By limiting the voltage level in the DC-bus to correspond to an actual need for a desired robot movement at each instant unnecessary fast robot movements are prevented even in the event that an inverter controlling motor currents would by mistake attempt to drive the motor faster than desired by the operator.
