【摘要】 随着电机工业发展，进入规模化生产的今天，中小型电机总产量每年以2％的幅度增长，为确保产品的高质量，每台电机出厂前都要进行参数检测，因此，国内研制一套高准确度、高自动化程度的中小电机自动测试系统对提高生产效率、减轻工作强度和提高质量都有重大的现实意义。 在交流伺服系统的控制中，经典的PID控制由于其结构简单、鲁棒性强以及方便现场对其使用和整定，而且它所涉及的控制算法和控制结构非常简单等原因，使它在目前的控制方案中依然是应用最广泛的控制策略之一。但由于电机本身存在非线性问题，如电枢反映的非线性、随负载和工况而变化的转动惯量、电阻变化等难以确定精确的数学模型的问题，使得传统的PID调节器在高精度伺服等场合难以保持良好的性能。 本文通过对智能电机测试与控制系统的设计分析，从现代控制理论方法中总结出来几种适应电机交流伺服系统的控制方法：模糊PID控制器和神经网络PID控制器，并对这2种方法进行仿真实验和实际系统的设计。通过对模糊PID控制器和神经网络PID控制器的仿真研究，得出：将先进的控制理论运用到传统的PID控制器中，其控制性能明显优于传统的PID控制器。 电机测试与控制系统的设计，不仅包括系统硬件的设计，还包括系统软件的设计。在本文中，作者对这两个方面做了比较全面的阐述。提出了一套切实可行的系统设计方案，供读者参考，同时，由于作者的水平有限，论文中可能存在许多不足之处，有待进一步研究。更多还原

【Abstract】 Developing along with the electrical motor industry, and entering the large scale production today, total yield of small scaled electrical motor every year is then 2% increased, and for insuring the product’s high quantity, each pedestal electrical motor outs from factory all want proceeding the automatic examination, therefore, domestic’s research to manufacture a high and accurate degree, high automation degree test System to increase the production efficiency, alleviate the work strength and increase the quantity is important with the realistic meaning.In the servo system of the control, the classic PID control, because of its construction simple, as to it’s the strong robust and convenient to apply, and that its calculate way and the construction are very simple, is now still one of the most extensive control strategies which applied. But because the electrical engineering esse is not line problem, reflecting with armature’s non-linearity, the inertia varying with load and work condition, the electric resistance variety and other mathematics model that difficult to accurate, the classic PID modulator is difficult to keep high accuracy with the good function in the servo situation.This paper sum up some kind of control strategies such as Fuzzy PID controller and NN PID controller in servo system from modern control theories method. Through design and simulation on intelligent electrical motor test and control system using this two kinds of methods, this paper summaries that: the PID controller’s function using modern control theories is obviously better than tradition of PID controller.The electrical engineering tests and control system’s design, and not only include the design of the system hardware, and still include the design of the system software. In this paper, author does more completely expatiation on these two aspects, and brings out a set system design in practice, providing the reader for reference, at the same time, because of author’s level in this field, thesis inside may exist the place of a lot of lack, need the further research.更多还原
