ROBUST CONTROL OF SYNCHRONOUS DRIVE WITH SYNCHRONOUS PERMANENT MAGNET MOTOR
Abstract:

Considered robust energy-saving control system of synchronous electric synchronous motors with permanent magnets. Energy optimization is carried out by calculating the optimal values ​​of the magnetizing current and the torque component of the stator using the coefficient proposed by the authors on the criterion of minimum power consumption ensures the formation of a given electromagnetic torque and minimizing energy consumption in real time.

To achieve robustness of the current controllers and speed controller are built using a combination of management of uncertainty estimation and compensation of external influences, mechanical and electrical parameters. To estimate the total uncertainty used observer uncertainty, the calculated value of further uncertainty is introduced into the control law so as to compensate for the impact of uncertainty, regardless of the reasons which caused it.

A distinctive feature of the proposed methods is robustness and ease of management and control system of calculation.
