The article proposes a concept of an automatic load cell control system with compensation of electromagnetic force for the tasks of precision force measurement. The following tasks were solved: mathematical modeling of mechanical processes in the compensation load cell when touching the cantilever, taking into account mechanical disturbances; identification of parameters and computer simulation of processes; development and simulation of the coil current control loop. The purpose of the control was to find a balance between precise control and reducing the oscillation of the control current.
