ELECTRIC DRIVE WITH AUTOMATIC CONTROL OF INPUT HARMONIC SIGNAL FREQUENCY Russian patent published in 2010 - IPC G05B13/00 B25J13/00 

FIELD: physics.

SUBSTANCE: invention additionally includes series-connected modulus evaluator whose input is connected to the output of a first adder, a second adder, a relay element, a memory unit whose data input is connected to the output of the modulus evaluator and through a delay device to the second input of the second adder, a third adder whose second input is connected to the output of a first signal selector, a first integrator, a second order low-pass filter, a fourth adder whose second input is connected to the output of a second signal selector, a second integrator, a sine function generator, a multiplier whose second input is connected to a third signal selector and the output to the second input of the first adder. An additional loop is formed for automatic setup of the maximum possible (for given dynamic error and amplitude of the input signal) frequency value of the drive signal.

EFFECT: provision for maximum possible displacement speed of the electric drive without exceeding the control dynamic error value based on information on the difference between the given and the current amplitude of the said dynamic error.
