ELECTRIC MOTOR ADAPTIVE CONTROL SYSTEM Russian patent published in 2017 - IPC G05B11/36 G05B13/02 H02P25/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in non-stationary objects automatic control systems – electric drive adaptive control systems. Electric drive adaptive control system additionally contains an associative memory, a differentiator, two multiplication units, three adders, a digital sensor of angular speed, three amplifiers, two delay units, three module determination units. Output of the digital angular speed sensor via series-connected the first delay unit, the second delay unit, the third adder, the first module determination unit, the associative memory, the first multiplication unit is connected to the second input of the second adder, the output of which via an digital-to-analogue converter is connected to the input of the electric motor, and via series-connected the second amplifier, the fourth adder, the second module determination unit – to the second input of the associative memory. Output of the digital angular speed sensor is connected to the second inputs of the first and the fourth adders, and via series-connected the fifth adder, the third module determination unit, the associative memory and the second multiplication unit - to the third input of the second adder. Output of the first delay unit is connected to the second inputs of the third and the fifth adders. Output of the first adder is connected via the third amplifier to the second input of the first multiplication unit, and via series-connected the fourth amplifier and the differentiator – to the second input of the second multiplication unit.

EFFECT: technical result is improvement of accuracy and stability margins by amplitude and by phase of the electric motor control system if affected by a coordinate-parametric interference.
