Based on running princijDlestor , the simulation model of the two-phase hybrid stepper motor open-loop control systemwas established.A parabolic acceleration and deceleration cure witli real-time calculation was designed aordinary constant and exponential-type acceleration and deceleration curves by simulation. Fexperimental study of different running curves was carried out. The simulation and experiment resultsshowthat the parabolic curve has faster dynamic response rate and smaller position tracking error, and issuitable for the applications that response speed is highly required. The proposed control strategy hasbeen successfilly applied in phase control of tiie phased aray antenna. stepper motor ＆ open-loop control; system modeling; acceleration and deceleration control; parabolic-type cure 23-1408/TM WANG Bang-ji , LIU Qing-xiang, ZHOU Lei , BU Lang, LI X |
