      基于DSP感應(yīng)電機變頻調(diào)速控制系統(tǒng)設(shè)計

      摘要:交流電機的變頻調(diào)速及其相關(guān)技術(shù)的研究是當前電氣傳動領(lǐng)域的1個重要課題,脈寬調(diào)制控制技術(shù)作為變頻調(diào)速中的1項關(guān)鍵技術(shù),在變頻調(diào)速技術(shù)的發(fā)展中具有重要的作用。而數(shù)字信號處理器(DSP)運算速度快,能夠完成復雜的控制算法,適合于建立高性能的調(diào)速系統(tǒng)。該系統(tǒng)設(shè)計在以TI公司16位定點DSPTMS320LF2407A為控制核心完成了感應(yīng)電機變頻調(diào)速系統(tǒng)的設(shè)計與研究。深入研究了變頻調(diào)速理論,正弦脈寬調(diào)制(SPWM)脈寬調(diào)制技術(shù),掌握了LF2407A的硬件結(jié)構(gòu)和編程方法。并以這種技術(shù)為理論基礎(chǔ),設(shè)計了PWM輸出程序,以及相關(guān)模塊的程序。完成了1個較為完整的感應(yīng)電機變頻調(diào)速系統(tǒng)的設(shè)計。通過電流、電壓、溫度、轉(zhuǎn)速檢測電路和顯示電路,實時將電機的運行狀態(tài)進行顯示。該系統(tǒng)通過鍵盤可以對電機的啟動、停止和轉(zhuǎn)速的上升、下降進行控制。

      Based on DSP asynchronous machine frequency conversion velocitymodulation control system design

      Abstract: The alternating current machine frequency conversionvelocity modulation and its the correlation technology research is acurrent electrical transmission domain important topic, thepulse-duration modulation control technology took in the frequencyconversion velocity modulation an essential technology, has the vitalrole in the frequency conversion velocity modulation technologydevelopment. But the digital signal processor (DSP) the operatingspeed is quick, can complete the complex control algorithm, suits tothe establishment high performance velocity modulation system. This system design in as the control core has completed Induction Electric motor  frequency Adjustable speed system design and the research take TICorporation 16 fixed points DSPTMS320LF2407A. Thoroughly has studiedthe frequency conversion velocity modulation theory, the sinepulse-duration modulation (SPWM) the pulse-duration modulationtechnology, has grasped the LF2407A hardware architecture and theprogramming method. And take this kind of technology as the rationale,has designed the PWM output routine, as well as correlation moduleprocedure. Has completed a more complete Induction Electric motor
      frequency Adjustable speed system design. Through the electric current, the voltage, the temperature, therotational speed examination electric circuit and the display circuit,real-time carry on the electrical machinery running status thedemonstration. This system through the keyboard may to the electricalmachinery start, stop with the rotational speed rise, the dropcarrying on the control.

      Keywords: Frequency conversion velocity modulation; DSPTMS320LF2407A;Sine pulse-duration modulation;
