【摘要】：本文以永磁同步電機為控制對象來研究其調(diào)速性能，考慮到永磁同步電機具有非線性、強耦合、多變量等特點，而傳統(tǒng)的控制器設計已不能滿足交流調(diào)速系統(tǒng)的更高性能的驅(qū)動要求，本文在傳統(tǒng)PID控制基礎上提出的一種改進型的模糊技術(shù)。該技術(shù)可以改善傳統(tǒng)的PID控制品質(zhì)，增強系統(tǒng)靈活性和適應性，有效提高永磁同步電機交流調(diào)速系統(tǒng)性能。論文的主要研究工作和成果如下： （1）利用坐標變換建立了永磁同步電機在三相靜止坐標系下和兩相旋轉(zhuǎn)坐標系下的數(shù)學模型，采用id0的矢量控制策略及電流環(huán)和轉(zhuǎn)速環(huán)的雙閉環(huán)控制方案，以電壓空間矢量脈寬調(diào)制（SVPWM）為調(diào)制算法，在此基礎上對矢量控制原理、SVPWM原理及其控制算法的設計與實現(xiàn)進行了詳細的分析。 （2）為了有效提高永磁同步電機PID調(diào)速控制系統(tǒng)的性能，研究了一種模糊自適應轉(zhuǎn)速控制器設計方法。利用MATLAB/simulink軟件建立了基于SVPWM的永磁同步電機模糊邏輯調(diào)速系統(tǒng)仿真模型，對電流環(huán)和轉(zhuǎn)速環(huán)分別采用PID控制、模糊自適應PID控制的PMSM系統(tǒng)進行了仿真，仿真結(jié)果驗證了模型的正確性和控制算法的有效性。 （3）選用德國Infineon公司的XE164芯片和功率驅(qū)動模塊6ED003L06F，并設計了完善的外圍電路，完成系統(tǒng)的硬件設計。系統(tǒng)軟件設計采用C語言和模塊化的程序思想。并搭建了軟硬件測試平臺。實驗結(jié)果表明，模糊自適應PID控制算法更能使調(diào)速系統(tǒng)具有良好的動、靜態(tài)特性。
[Abstract]:In this paper, permanent magnet synchronous motor is used as the control object to study its speed performance. Considering that PMSM has the characteristics of nonlinear, strong coupling, multivariable and so on, the traditional controller design can not meet the higher performance requirements of the AC speed control system. An improved fuzzy technique based on the traditional PID control is proposed in this paper. The technology can improve the traditional PID control quality, enhance the flexibility and adaptability of the system, and effectively improve the performance of the PMSM AC speed control system. The main research work and results of this paper are as follows:
(1) the mathematical model of the permanent magnet synchronous motor in the three-phase stationary coordinate system and the two phase rotating coordinate system is established by using the coordinate transformation. The vector control strategy of id0 and the double closed loop control scheme of the current loop and the speed ring are adopted, and the voltage space vector pulse width modulation (SVPWM) is used as the tuning algorithm. On this basis, the vector control principle, the original SVPWM The design and implementation of the control algorithm and its control algorithm are analyzed in detail.
(2) in order to effectively improve the performance of PID speed control system of permanent magnet synchronous motor, a design method of fuzzy adaptive speed controller is studied. The simulation model of fuzzy logic speed control system of permanent magnet synchronous motor based on SVPWM is established by using MATLAB/simulink software, and PID control and fuzzy adaptive PID are used for the current loop and speed loop respectively. The PMSM system is simulated, and the simulation results verify the correctness of the model and the effectiveness of the control algorithm.
(3) select the XE164 chip and power drive module 6ED003L06F of German Infineon company, and design a perfect peripheral circuit to complete the hardware design of the system. The system software design adopts the C language and the modularized program thought. And the software and hardware test platform is built. The experimental results show that the fuzzy adaptive PID control algorithm can make the speed regulation system more effective. The system has good dynamic and static characteristics.
