abstract={The appearance in recent years of the two-motor electric drives on the presses of high speed paper machines ensures increasing of the life of expensive press felts and improvement of production quality. The easiest and accurately acting from the different existing control systems of drives are two-motor drives with a total speed controller and individual thyristor converters for each motor separately. In this paper we study the dynamic characteristics of the system with a digital controller and correctors. The mathematical model of two-motor thyristor electric drive, taking into account the elastic properties of mechanical transmissions, is given. Applying the logarithmic frequency characteristics for tuning of digital controllers, correctors and current sensors of the drive system are given. The results of investigations of transient processes using the MATLAB sources are presented. This system guarantees maximum performance and proportional distribution of load between the motors without any additional controllers.},
