Guidance Control Method of Hybrid Excitation Guidance System

Abstract

The invention relates to a guidance control method of a hybrid excitation guidance system and aims at solving non-contact guidance adjustment of a hybrid excitation suspended guidance system. The guidance control method is characterized in that the hybrid excitation guidance system comprises a rotor guidance component formed by a permanent magnet control winding and an electric excitation control winding and a stator square track; and permanent magnet generates an inherent bias magnetic field, the two independent control windings generate an adjusting magnetic field, the permanent magnetic field and the current adjusting magnetic field generate guidance control force by common action with the stator square track. Current is introduced into the two control windings simultaneously to generate X-direction electromagnetic force, simultaneously opposite-direction same-value current is introduced to generate Y-direction electromagnetic force, the sizes and the directions of the currents of the two control windings are combined in a different manner, and X-direction and Y-direction displacement control of the rotor guidance component is realized by a current controller. The guidance control method provided by the invention solves the non-contact guidance adjustment of the hybrid excitation suspended guidance system.

Description

technical field [0001] The invention relates to a guidance control method of a hybrid excitation guidance system. Background technique [0002] With the development of social economy, people are building more and more high-rise and super high-rise buildings. For example, the Burj Khalifa in the United Arab Emirates is 828 meters high and has 162 floors; the Mecca Royal Clock Tower Hotel in the Kingdom of Saudi Arabia is 601 meters high. , a total of 95 floors; the Shanghai Tower is 632 meters high, with a total of 125 floors; Taipei 101 Financial Center is 509 meters high, with a total of 106 floors; the Petronas Twin Towers in the capital of Malaysia is 457 meters high, with a total of 88 floors. Several other skyscrapers are currently in the planning and construction stages. With the continuous increase of floor height, it is necessary to configure high-speed elevators. The traditional mechanical guide wheel or sliding shoe contact guidance method can no longer meet the n...
