摘　　要：在绕线机控制系统中,线速度与角速度之间具有非线性,采用常规的PI控制器对线速度进行控制时很难取得满意的控制效果,在矢量控制的基础上,提出并实现了永磁同步电机的线速度控制系统,分析并推导了线速度控制模型,重点进行了线速度控制器的设计,为便于工程应用,给出了线速度控制器的离散控制算法,相对于常规的PI控制器,系统具有过渡过程平稳,控制精度高,鲁棒性好的优点。最后介绍了基于数字信号处理器(DSP)的硬件控制平台,以及电流环、转速环和线速度控制环的软件控制流程,仿真实验结果表明控制算法的有效性和工程实用性。In coiling machine control system,the linear velocity is nonlinear to the angular velocity.It is hard to achieve the approving control effect when performing the linear velocity control using conventional PI controller.On the basis of vector control,a permanent magnet synchronous motor（PMSM） linear velocity control system was implemented.The linear velocity control model was derived and the linear velocity controller design was processed emphatically.The discrete expressions of linear velocity control algorithm were given for the convenience of engineering application.Compare with the control effect when using conventional PI controller,the system has merits of smooth transition process,high control precision and good robust characteristic.Hardware control platform based on digital signal processor（DSP） and software flow chart of current loop,angular velocity loop,linear velocity loop were introduced at last.Simulation results verify the effectiveness and engineering practicability of the proposed approach.
