The article is devoted to the solution of the problem of synthesizing self-adjusting correction devices (SCD) for brushless DC motors (BLDC) used as actuators of various mechatronic systems, including multi-stage manipulators and mobile robots. The specified correction devices allow to significantly increase the dynamic control accuracy of these loaded motors by generating an additional control signal fed to the input of the electronic speed controller of the motors. These ensures stabilization during operation at a given nominal level of their dynamic parameters taking into account the current values of external load moments reduced to their output shafts. To solve this problem, an equivalent model of a BLDC described by a system of three first-order differential equations and a method for synthesizing typical SCDs for collector motors are used. The use of an equivalent BLDC motor model made it possible to significantly simplify the control law obtained and reduce the power requirements for on-board computers of robotic systems. To confirm the efficiency of the synthesized SCDs, modeling and a full-scale experiment using an electromechanical stand were carried out. The experimental results confirmed the ability of the developed system to impart specified dynamic properties to the motor.
