摘要
交流电机作为工业系统及日常生活中最常见的运动执行器,对其转速进行控制具有重要意义。基于计算机的电机调速系统应用越来越广泛。本设计主要包括以下三个部分:1)总体设计方案分析与设计:硬件设计光电转换及信号调理电路设计、频压转换电路设计。电动机及变频器(驱动装置)、A/D及其D/A板选择等。2)软件设计:系统管理程序、控制算法设计及信号的采集与处理程序等。本文主要侧重点是软件设计利用传统的PID设计,控制效果非常理想,满足工业生产的应用。智能控制算法作为当今控制系统的研究热点问题,我们也进行了深入的学习,分别利用模糊自适应控制算法和单神经元自适应控制算法,所得到的效果也是非常理想的。将模糊控制和PID控制相结合,提出了一种智能复合控制策略,并将其应用于交流伺服系统的控制。利用模糊控制在线自适应调整PID控制器的参数,从而使系统的静态和动态性能指标较为理想。实验结果表明,基于模糊PID控制的交流伺服系统具有响应速度快,稳态精度高和鲁棒性等特点。最后,进行GUI(图形用户界面)设计,实习控制系统的可操作性和可视化。此外本文还针对实际设计中遇到的问题进行了分析和讨论,提出了参考方案,本次速度控制系统设计经历了很多改动,可以看出控制系统在设计思想和技术上进步。

Abstract
AC motor as the most common industrial systems in daily life and movement of the actuator, is of great significanceto control the speed of. Based on the application of computer motor speed control system is more and more widely. This design mainly includes the following three parts: 1) analysis and design of overall design: HardwareDesign of photoelectric conversion and signal conditioning circuit, frequency voltage conversion circuit design.Motor and inverter (drive), A/D and D/A board etc.. 2) software design: system management procedures, control algorithm design and signal acquisition and processing etc.. This paper mainly focuses on software design usingthe traditional PID design, the ideal control effect, meet the application of industrial production. The intelligent control algorithm as the hotspot problem of the control system, we also conducted in-depth study, using fuzzy adaptive control algorithm and single neuron adaptive control algorithm, the effect is very ideal. The combined with fuzzy control and PID control, a composite control strategy, and applied to the control of AC servo system. Usingfuzzy control to adjust the parameters of PID controller online, so that the static and dynamic performances of the system is ideal. The experimental results show that, the AC servo system based on fuzzy PID control has quick response speed, high steady-state precision and robustness etc.. Finally, the GUI (graphical user interface)design, operation and visualization practice control system. In addition, according to the actual engineering problems are analyzed and discussed, put forward the reference scheme, the speed control system design has experienced many changes, we can see that the control system design idea and technical progress.
