【正文】 實驗證明該控制系統(tǒng)方案具有良好的控制性能，具有 較好的實用價值。中斷服務(wù)程序主要有 PWM同步中斷服務(wù)程序，每次電流采樣 A/D轉(zhuǎn)換結(jié)束后產(chǎn)生中斷。當(dāng)電機電流與電動車車速嚴(yán)重不相關(guān)時，即使電機電流沒有達到限流設(shè)定值，如果電機電流大于 8A，控制器首先減流到 8A 供電，然后再次判斷車速與電機電流的相關(guān)性，在相關(guān)范圍內(nèi)，進入正常供電模式 。對電源電壓進行 AID 轉(zhuǎn)換之后，如果欠壓，當(dāng)次欠壓標(biāo)志位置一，使能定時器 0中斷，開始定時，欠壓滿 5秒之后停機，跳到自檢工作模式。軟件設(shè)計中遇到的 PI調(diào)節(jié)器設(shè)計問題即比例系數(shù) kP和積分作用系數(shù) ki選取問題。 ADSP21992 為 160 M 的高性能混合信號 DSP芯片，該芯片除具有強大數(shù)據(jù)處理能力外，針對電機控制，還提供有 6 路 PWM 輸出、 8 路 14 位A/D 轉(zhuǎn)換通道、 16 路通用 I／ 0口以及 3個 32 位專用計數(shù)單元等硬件資源。系統(tǒng)最終的目標(biāo)是應(yīng)用于飛輪系統(tǒng)中的高速無刷直流電機，因此，對處理器的速度要求極高，從實時性能方面考慮，需要選取處理速度盡可能高的芯片。 when the motor current and speed of electric vehicles is not related to serious, even if the electric current does not meet current limiter settings, if the motor current is greater than 8A, the controller 8A first cut into the power supply, and then again with the motor speed to determine the relevance of current in the relevant context, into the normal power supply mode。 drive circuit using IR39。 and as a result of not required excitation power, efficiency is relatively high, it has been rapid development. A pany based on ADI39。s ADSP21992 chip highspeed brushless DC motor control system, which has a highspeed, high load moment of inertia, have greater motor starting torque characteristics. DSPbased motor control system with the traditional singlechip motor control system and a dedicated chip motor control system, that is, a dedicated motor control mechanisms, userprogrammable, scalable, and powerful, and so on。s I82130 dedicated MOs power device gate drive dedicated chip, the chip can not only achieve the optimal IGBT driver, and has a perfect protection, can significantly improve system integration and reliability。 If there is no relevance, Further reduce the power flow controller.
