基于DSP的直线电机位置伺服控制策略研究

在综合分析直线电机位置伺服控制系统的动静态性能及抗干扰能力的基础上，对其位置伺服控制策略进行了研究，开发了一套基于DSP的直线电机位置伺服控制系统。该伺服系统提出了用模糊自适应PID控制方法和干扰观测器补偿技术来提高系统的动静态性能，且可以补偿因外力等对系统造成的干扰。重点分析了位置角对系统的影响，进而提出了模型参考自适应算法对位置角进行校正以消除直线电机定位时出现的振荡。实验结果表明，所提出的位置伺服控制系统具有高的动、静态性能。

Research on the DSP-based control strategies of a positioning servo system of the linear motors

Based on the synthetic analysis of the dynamic and static performance and anti-disturbance ability of a position servo control system for linear motors, the position control is studied strategy and a DSP-based position servo control system is developed. A fuzzy adaptive PID controller and a disturbance observer for the control system are proposed to promote its dynamic and static performance and compensate the outside disturbance imposed by outside force or other factors. Furthermore, the influences of the position angle on system are analyzed and model reference adaptive algorithm is proposed to correct the position angle in order to eliminate vibration of linear motors while positioning. Experiment results show that the proposed position servo control system has much high dynamic and static performance.
