Electric drive systems are widely used in most sectors of the national economy. The basic task of the system is to convert electrical energy into mechanical energy and control that conversion process in working machines, especially in modern automatic production lines. Automatic electric drive systems play an important role in improving productivity and product quality. The control theory of a system with a variable structure is a difficult theory, based on the theory of differential equations with a discontinuous right-hand side. The sliding control method needs to be studied in more detail so that it can be applied to synthesize controllers for non-linear, non-stationary systems, under the motion of unknown components, disturbances...
