Design And The Simulation Of The Linear Step Motor Control System

This paper introduced a micro-computer control system of the linear step motor. Based the characteristics of the linear step motor and met the need of the control, we chose the special motor control chip DSP (digital signal processor) TMS320F240 to realize a open loop control .Through it we got the SPWM to control our system .To reduce the vibration ,we induced the best control of the whole system. Through the hardware and the software design, precise positioning can be realized.To build the model of the linear step motor, a centralize-parameter circuit theory was used .The model was simulated under the MATLAB/SIMULINK environment and got the force-displacement characteristic curve.At last , we designed the experiment equipments and used it to validate the correction of the whole system.
