Abstract


With the development of technology, the motion control system is applied in all aspects of power electronics technology, control technology , AC drive technology and other advanced technology to become the core of the drive control technology . The emergence of so many high-performance stepper motor drive control has been further developed to overcome the stepper drive control to the main obstacle to the development of large capacity , stepper motion control has entered a new period of development. This paper describes the development of the stepper drive and switched reluctance motor of the basic structure and working principle , as a step on the switch reluctance motor drive control system theory , in -depth analysis of switched reluctance motor magnetic potential , transfer moment and the stator based on the relationship between current , proposed direct control of the momentary torque current of the motor directional control method of the torque and the stator current is given between the expression , to overcome the static angle error , improve the system positioning accuracy. This article from the starting characteristics of the system , load anti-jamming features two aspects of the stepper drive control system dynamic characteristics analysis . According to the system 's performance indicators, selected harmonic reducer , inertia wheel, multi-pole rotary transformers build dynamic test platform , and in the stator current directional control theory , the design of the switched reluctance motor control system structure . Controller produced by TI DSP chip TMS320LF2407A as control core , ensure the realization of switched reluctance motor stator current orientation control . Finally, build a test platform , using current directional control strategy, validate switched reluctance motor stepper motion control system has good dynamic characteristics, for optimal control and energy-saving control provides a theoretical basis .
