TRACKING DRIVE FOR STABILIZATION OF ROLLING AND PITCHING Russian patent published in 2022 - IPC H02P8/12 

FIELD: automation.

SUBSTANCE: invention relates to the field of automation. The tracking drive for stabilization of side roll and pitching provides angular stabilization of the platform in the horizon plane and can be used as ship equipment. It includes a current regulator that implements vector control of a three-phase electric motor with PID controllers of the longitudinal and transverse components and adaptive tuning, PI speed controller with symmetric optimum tuning and P-position controller with linear optimum tuning, as well as a pitching simulator and a cross-influence compensation unit. The roll simulator provides a more accurate presetting. The cross-influence compensation unit reduces the influence of disturbing influences on the accuracy of the task signal processing. The regulators ensure the minimization of the dynamic tracking error at a harmonic reference signal and high angular velocities and angular accelerations.

EFFECT: invention increases accuracy of stabilization of the platform installed on the ship is ensured, including during significant rolling.
