【正文】 如果在相關(guān)范圍內(nèi)，控制器以不超過限流設(shè)定值為依據(jù)控制電動(dòng)車車速 。 基于 DSP 的電機(jī)控制系統(tǒng)具有傳統(tǒng)的單片機(jī)電機(jī)控制系統(tǒng)和專用芯片電機(jī)控制系統(tǒng)的優(yōu)勢，即專用的電機(jī)控制機(jī)制、用戶可編程、擴(kuò)展能力強(qiáng)、功能強(qiáng)大等；同時(shí)又克服了它們各自的缺點(diǎn)，如外設(shè)和 存儲器集成在芯片內(nèi)，可減少電路板面積、減少系統(tǒng)中元器件個(gè)數(shù)、提高 CPU 處理能力、提高系統(tǒng)的可靠性等。 at the same time, overe their respective shortings, such as peripherals and memory integrated into the chip to reduce circuit board area, reducing the number of system ponents to improve the CPU processing capacity, improve system reliability. System, the ultimate aim is the application of highspeed flywheel system brushless DC motor, therefore, very high speed processors, from the realtime performance to consider, Need to select the highest possible processing speed of the chip. 2199x series and ADI39。 3．轉(zhuǎn)子位置及電流檢測電路 由于高速電機(jī)工作電流、反電勢波形畸變較為嚴(yán)重，因此不適合采用無位置傳感器控制，為安裝方便，采用體積小、安裝 方便的電磁霍爾傳感器并安裝于定子繞組端部，輸出信號經(jīng)分壓，濾波緩沖。最優(yōu)化，系數(shù)的選取有待進(jìn)一步的實(shí)驗(yàn)與研究。過流保護(hù)是控制器的最后防線，過流保護(hù)電阻用的是康銅絲，當(dāng)系統(tǒng)電流超過最大保護(hù) 電流值時(shí)，康銅絲會燒斷，從而起到保護(hù)作用。介紹一種基于ADI 公司 ADSP21992 芯片的高速無刷直流電機(jī)的控制系統(tǒng)，該系統(tǒng)具有高速、大轉(zhuǎn)動(dòng)慣量負(fù)載，電機(jī)有較大起動(dòng)轉(zhuǎn)矩等特點(diǎn)。s speed reached 160 M, and then to adapt to take into account their poor working environment, in this paper, we have chosen the ADSP21992 as a core control chip. (A) hardware 1. Control circuit Mainly by the control circuit and its corresponding external ADSP21992 expansion circuit. Including the crystal oscillator circuit, extend outside the FLASH, JTAG interface, power supply voltage conversion circuit, PWM interface, 1 / 0 interface and A / D interface circuit modules. ADSP21992 for the 160 M highperformance mixedsignal DSP chips, the chip in addition to a powerful dataprocessing capabilities, for motor control, but also to provide 6channel PWM output, 8channel 14bit A / D conversion channels, 16 generalpurpose I / 0 I, as well as thr
