传统的永磁同步电动机控制器设计方法一般需要对系统参数进行准确的了解，不过在实际操作过程中，系统参数往往会发生变化，为了确定系统的稳定性能必须得由相应的控制器来进行调整。模糊控制等智能控制策略，都具有独立于对象的数学模型，鲁棒性强的优点，可以克服伺服系统参数和非线性因素等不确定性，从而实现高质量的控制系统性能。

在该系统中，为了满足高性能控制的要求，模糊控制作为高品质的控制策略，满足永磁同步电机全数字实时控制性能要求。在一个不确定，不准确和嘈杂的环境中提高系统性能。目前，电机伺服系统中的模糊控制有许多成功的例子。由于模糊控制系统设计不需要准确的数学模型和强鲁棒性，结合其他智能控制方法的优点，这使得伺服系统的高精度性能以及高品质控制策略的设计成为了可能。然而我们有理由相信工业过程控制和电气控制应用中的模糊控制将会越来越广泛。

Design of Speed Sensorless Permanent Magnet Motor Based on Fuzzy Control

Abstract: With the rapid development of science and technology, Permanent magnet synchronous motor speed control system in control accuracy and dynamic performance has been greatly improved, has been close to the level of DC speed control system, with good reliability and maintenance characteristics, has been gradually Become the mainstream of the field of speed。 High-performance permanent magnet synchronous motor speed sensorless vector control system is one of the biggest hotspots in AC inverter research。 Because of its system in the speed sensor, both can save costs, can also increase the stability of the system, widely used in a variety of different occasions。

The traditional permanent magnet synchronous motor controller design method generally requires an accurate understanding of the system parameters to control the legal requirements, but in practice, the system parameters tend to change to ensure that the excellent system performance must be controlled by the corresponding controller Make adjustments。 Fuzzy control and other intelligent control strategies are independent of the object of the mathematical model, the advantages of strong robustness, can overcome the servo system parameters and non-linear factors such as uncertainty, in order to achieve high-quality control system performance。

In this system, in order to meet the requirements of high-performance control, the fuzzy control is adopted as the high-quality control strategy to meet the performance requirements of all-digital real-time control of permanent magnet synchronous motor。 , Improving system performance in uncertain, inaccurate and noisy environments。 At present, fuzzy control in the motor servo system has many successful examples。 Because the design of fuzzy control system does not need accurate mathematical model and strong robustness, combined with the advantages of other intelligent control methods, We have good reason to believe that this industrial process control and electrical control applications in the future will be more and more extensive fuzzy control。
