摘　　要：针对传统直线运动采用旋转电机与滚珠丝杠结合的方式存在效率和精度低等现象,设计了一种以数字信号处理器(DSP)为核心的直线电机伺服控制系统,重点研究和分析了控制系统的数学模型与控制系统设计,完成控制系统硬件平台和软件程序流程的设计。采用的矢量控制方法实现电流解耦控制,将模糊控制与传统的PI控制相结合,设计一种模糊自适应PI控制器,在MATLAB/Simulink环境下进行仿真,并进行现场实验和验证。仿真和实验结果表明,该控制系统能有效提高直线运动系统速度及定位精度,并且结构简单,稳定性好,可靠性高。Linear movement consisting of the traditional rotary motor and ball screw has shown many weaknesses ,such as the low precision and low efficiency. It designs a digital signal processor （DSP） core of the linear motor servo control system, and focuses on analysis of the control system mathematical model and control system design, and completes control system hardware platforms and software applications process design. Adop control strategies to achieve the current decoupling, the fuzzy control and traditional PI control combined to design a fuzzy adaptive PI controller, and simulates in MATLAB/Simulink environment, and field experiments and validation. Simulation and experimental results show that the control system can effectively improve the speed and position precision of the linear motor system, and it has a simple structure, good stability and high reliability.
