Design and Implementation of Position Control Algorithm for Linear DC Motor

为了实现一种动圈型永磁直线直流电机的位置伺服控制,提出了基于对象模型的位置前馈跟踪控制算法,并对该控制策略的数字化实现方法进行了分析。基于TI公司的DSP开发平台,采用模块化程序设计方法,阐述了软件设计的主要功能模块及相关寄存器的设置,给出了软件流程图。实验结果表明,在采样周期为0.2ms时,位置前馈跟踪控制算法可得到较小的位置跟踪偏差。

In order to implement the position servo control of a moving-coil type PM linear DC motor,a position feedforword tracking control algorithm based on object model was proposed.The digitized controller was presented.Based on TI DSP development platform and the modularized program method,the main software function module and register set were discussed.During 0.2 ms sampling period,the experiments results show the effectiveness of the proposed control algorithm and the control system with the acceptable position tracking error.
