Abstract

The present invention provides a linear motor-based electro-mechanical actuator control system and a control method, and relates to the field of design of a linear motor control system and an electro-mechanical actuator. The linear motor-based electro-mechanical actuator control system consists of a linear motor, a grating scale, a power supply conversion board, a grating decoding module, a digital controller, and a driver; wherein a main program of the digital controller acquires a position feedback value outputted by the grating decoding module, an actuator position instruction which is externally inputted, and a current detection value transmitted by the driver to perform control rate operation, so as to obtain turn-on and turn-off signals of switching tubes of the driver, and transmits the signals to the driver to actuate the linear motor. In comparison with an electro-mechanical actuator adopting a conventional ball screw structure, the linear motor-based electro-mechanical actuator control system has the advantages that the structure is simplified, components are simplified, and better actuation characteristics are achieved on a high-thrust and high-dynamic linear actuation occasion.
