Power optimizing control of grinding process in electromagnetic mill

The paper presents optimizing control of the electromagnetic grinding system. The electromagnetic grinding is a complex process, thus formulation of the optimization problem is done in a top-down manner. To do so, the parameters which influence product quality and serves as decision variables are specially selected. The selection follows from environmental analysis of the system and discussion of the dynamics of disturbances which affect the grinding process. The criterion function to be minimized is electrical energy consumption. Algorithms solving optimization problem are described in the paper. The optimizing control performs as adaptive-like system where minimum energy is kept by proper control of the inverter. Control system constitutes an element of SCADA layered structure.
