摘 要:開(kāi)關(guān)磁阻電機(jī)（SRM）作為一種新型的特種電機(jī)，以其結(jié)構(gòu)簡(jiǎn)單堅(jiān)固、低成本、高容錯(cuò)性能以及高速運(yùn)行的能力，越來(lái)越廣泛地應(yīng)用于牽引運(yùn)輸、航空航天、家用電器等各個(gè)領(lǐng)域中，具有很大的潛力。而要對(duì)SRM進(jìn)行深入的理論分析，就需要對(duì)其建立一個(gè)準(zhǔn)確而又有實(shí)用性的模型。而開(kāi)關(guān)磁阻電機(jī)調(diào)速系統(tǒng)（SRD）一個(gè)多變量、強(qiáng)耦合的非線(xiàn)性系統(tǒng)，在不同的控制方式下，其參數(shù)和結(jié)構(gòu)都是變化的，這使得傳統(tǒng)的線(xiàn)性控制方法（如PID 控制）難于滿(mǎn)足SRD的動(dòng)態(tài)性能要求。而MATLAB軟件具有強(qiáng)大的矩陣和數(shù)學(xué)計(jì)算功能，利用它的模塊之一SIMULINK建模有著界面友好、易于進(jìn)行參數(shù)修改等特點(diǎn)。 模糊控制技術(shù)（FLC）作為智能控制的一個(gè)重要分支，它通過(guò)采用人的控制知識(shí)，作用于非線(xiàn)性被控對(duì)象的控制時(shí)表現(xiàn)出良好的特性。FLC提供了一個(gè)用模糊規(guī)則來(lái)表達(dá)、控制和實(shí)現(xiàn)人的關(guān)于如何控制一個(gè)系統(tǒng)的方法。很多應(yīng)用證明了FLC是適合應(yīng)用于具有很強(qiáng)非線(xiàn)性特性的SRM控制的。 通過(guò)MATLAB對(duì)應(yīng)用FLC的SRM進(jìn)行仿真分析，得到一些仿真的響應(yīng)波形，雖然有一些波形與理論不是太吻合，但是通過(guò)不斷調(diào)節(jié)FLC的參數(shù)，使得響應(yīng)波形達(dá)到最理想的狀況。 關(guān)鍵詞：開(kāi)關(guān)磁阻電機(jī) 非線(xiàn)性系統(tǒng) 模糊控制技術(shù) 模糊規(guī)則 響應(yīng)波形
ABSTRACT:As a new type of special motor, Switch Reluctance Machine（SRM）has great potential perspective, which has been popularized to be applied to all kind of fields, for instance, traction transport，aeronautics and astronautics,household appliances and so on. The reason why it is popular that it has many benefits, including simple and solid structure, low cost, high fault-tolerance performance and high speed operation ability. It needs to establish an accurate and practical model to make an in-depth theoretical analysis for SRM. As we all known, Switch Reluctance Drive (SRD) is a muti-variable, strong coupling nonlinear system, so its’ parameters and structure are continuous change under different control model, which is difficult to makes the traditional linear control methods (such as PID control) satisfy the dynamic performance requirement of the SRD system. However, MATLAB software has strong matrix and the mathematical calculation function, using the one of module of SIMULINK to model, which has many characteristics, such as providing friendly interface, modifying parameters easily. As an important branch of intelligent control, Fuzzy Logic Control (FLC) shows good properties, acting on the nonlinear object controlled, by using the knowledge of people. FLC provides a method that fuzzy rules can express and control system and achieve how to control it. Many application proves that the FLC is suitable for application in SRM control, which has strong nonlinear feature. Through MATLAB simulation analysis on the adoption of SRM applied FLC, it can get some simulated response waveforms. While there are some waveforms disaccord with theory, it can achieve the ideal response waveform by constantly adjusting the parameters of FLC.
