The embodiment of the invention relates to a method and device for processing a target object and a storage medium. The method comprises the steps that first sampling data about multiple sampling moments of the target object and second sampling data about multiple sampling moments of a first motor and a second motor are acquired; determining a first real-time rolling diameter of the target object on the first roller and a second real-time rolling diameter of the target object on the second roller according to the first sampling data and the second sampling data; and according to the first real-time rolling diameter and the second real-time rolling diameter, the torque and / or the angular speed of the first motor and / or the second motor are / is adjusted, so that the tension stability and / or the linear speed stability of the target object are / is maintained. According to the technical scheme, the tension stability and / or the linear speed stability of the target object can be maintained, so that the spray dyeing effect is improved.

A method for controlling an electrical converter system (10), comprising: determining a switching signal (u*) within a range of future sampling instants abc ) and a reference trajectory (Y*) of at least one electrical quantity of the electrical converter system (10) αβ ), where the switching signal (u* abc ) and the reference trajectory (Y* αβ ) is determined from the optimized pulse pattern (A*, U*) table, the switching signal (u* abc ) includes switching transitions between output levels of the electrical converters of the electrical converter system (10), and a reference trajectory (Y* αβ ) indicates a desired future trajectory of at least one electrical quantity of the converter system (10); from a switching signal (u* abc ) generates the average switch position (V* abc ) sequence, where the switching signal (ua* bc ) is divided into sampling intervals, the average switch position (V* abc ) sequence includes the average switch position (V* abc ), the average switch position is defined by the switching signal (u* abc ) is determined by averaging; by abc ) to determine the optimal average switch position (V* abc ) of the optimized average switch position (V abc ) sequence, the cost function (J) includes the reference trajectory (Y* αβ ) and the predicted trajectory, wherein the predicted trajectory is determined from a model of the converter system within the range, into which the modified average switching position sequence of the converter system and the measurement results are input; by shifting the switching signal (u* abc ) to determine the optimal switching signal (u abc ), so that in the current sampling interval, the switching signal (u abc ) is equal to the average value of the optimized switch position (v abc ); and the optimized switch signal (u abc ) is applied to the electrical converter system (10).
