基于DSP28035的高速永磁無(wú)刷直流電機(jī)驅(qū)動(dòng)系統(tǒng)，包括論文和軟硬設(shè)計(jì)資料。摘要參賽作品為基于DSP28035的高速永磁無(wú)刷直流電機(jī)驅(qū)動(dòng)系統(tǒng)。該系統(tǒng)以一臺(tái)額定轉(zhuǎn)速60 krpm的高速永磁無(wú)刷直流電機(jī)、交錯(cuò)并聯(lián)的Buck電路以及全橋電路為硬件平臺(tái)，以DSP28035為控制核心，實(shí)現(xiàn)了調(diào)壓調(diào)速功能和基于坐標(biāo)變換的無(wú)位置傳感器新技術(shù)。為實(shí)現(xiàn)該系統(tǒng)要求，本作品充分利用了DSP28035的資源例如：CLA模塊，模擬比較器、HPWM模塊以及AD轉(zhuǎn)換模塊等。AbstractThis work is the drive system for a high speed permanent magnet burshless dc motor based on DSP28035. The hardware platform consists of a BLDC motor(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the motor’s speed with voltage and the function of sensorless control based on the coordinate transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁無(wú)刷直流電機(jī)驅(qū)動(dòng)系統(tǒng)由于基波頻率較高（一般在1kHZ以上），利用逆變橋斬波進(jìn)行調(diào)速的控制方式通常會(huì)受到開關(guān)管開關(guān)頻率的限制，因此該系統(tǒng)多采用三相全橋前級(jí)加Buck電路進(jìn)承擔(dān)調(diào)壓調(diào)速的功能，而三相全橋主要承擔(dān)邏輯換相的功能。然而，傳統(tǒng)Buck電路所需電感的體積較大，增加了系統(tǒng)的體積，降低了系統(tǒng)的功率密度。
