Abstract

There are a number of installations and technological processes, the movement of which is carried out by an external source of energy, and the electric machine, not being the main source of movement, constantly or periodically is in the mode of electric generating braking to provide the desired characteristics of the workflow.
The problem solved in this research is to expand the functionality of the generator and the motor in the electric braking mode. The problem is solved by an automatic control of the coordinates of the electric machine in the generator mode. A feature of the proposed control method is that one or more coordinates of a generator or motor in electric braking mode are forcibly set by an external energy source, and the goal of coordinated regulation of other coordinates of an electric machine is to provide a given law for converting mechanical energy into electrical or an algorithm for the movement of an executive object of a working machine.
The article presents example of the synthesis of regulated electric drive control algorithms based on the principle of coordinated control of coordinates. The example concerns the synthesis of the law of motion control of an electric vehicle in the regenerative braking mode, in which a constant value of deceleration is ensured under conditions of an alternating force of resistance to movement and the moment of inertia of a moving object.
The proposed approach to the synthesis of generator mode control laws of electric machines, through the use of the principle of coordinated control of coordinates, acquires qualitatively new properties, as compared with traditional methods of electric braking, increases the technical and economic indicators of the electromechanical system as a whole.
