數(shù)字控制的交流調(diào)速系統(tǒng)所選用的微處理器、功率器件及產(chǎn)生PWM波的方法是影響交流調(diào)速系統(tǒng)性能好壞的直接因素。在介紹了正弦脈寬調(diào)制(SPWM)技術的基礎上,設計了一種以8098單片機作為控制器,以智能功率模塊IPM為開關器件的變頻調(diào)速系統(tǒng)。通過軟件編程,產(chǎn)生正弦脈沖寬度調(diào)制波形來控制絕緣柵雙極晶體管的導通和關斷,從而達到控制異步電動機轉(zhuǎn)速的目的。實驗結(jié)果表明,該系統(tǒng)可調(diào)頻率調(diào)電壓,穩(wěn)定度高,調(diào)速范圍寬,具有較強的實用價值 Abstract: AC variable speed with digital control systems used microprocessors, power devices and generate PWM wave is the direct factors of affecting the performance AC speed regulation system. On the BASIS of introducing the sinusoidal pulse width modulation (SPWM) technology,this paper designed variable speed system which used 8098 as a controller, intelligent power module IPM as switching device. Through software programming, resulting in sinusoidal pulse width modulation waveform to control the insulated gate bipolar transistor turn on and off, so as to achieve the purpose of speed control of induction motors. Experimental results show that the system can adjust frequency modulation voltage, high stability, wide speed range, has a strong practical value.

為解決電致變色器件的顏色變化受外界環(huán)境顏色控制的問題,設計了一種基于單片機的便攜式顏色自適應識別電路。與傳統(tǒng)顏色識別電路相比較,該電路利用數(shù)字式的顏色傳感器來獲取外界環(huán)境顏色,產(chǎn)生的數(shù)字顏色信號易于單片機進行處理。在電路中,下位機部分主要負責獲取電致變色器件變色參數(shù)及控制電致變色器件的顏色變化;而上位機部分主要負責把下位機獲取的電致變色器件變色參數(shù)進行電壓到顏色的曲線擬合,并通過藍牙通信把擬合曲線參數(shù)傳遞給下位機。結(jié)果表明,該電路能自動根據(jù)環(huán)境顏色提供-4~4 V范圍步進為0.1 V的電壓來驅(qū)動電致變色器件的顏色顯示,與傳統(tǒng)的顏色識別電路設計相比,識別的精度和速度都得到了明顯改善。 Abstract: In this paper, a portable adaptive circuit for color identification(PACCI) based on MCU was designed. Compared to the traditional color identification circuit, the PACCI adopts digital sensor to detect the color data from external environment and further generate digital color data, which can be processed easily by MCU. In PACCI, the slave is mainly responsible for detecting the color parameters of the corresponding elcreochromic device and further driving it. For the master, which is mainly responsible for the color curve fitting based on the parameters of the electrochromic device, and transmits the fitting parameters to the slave through the bluetooth device. The results show that the PACCI can provide the BASIS voltage range from -4V to 4V automatically based on the colors of external environment with step as 0.1V to drive the corresponding electrochromic device. Compared to the traditional color recognition circuit, the recognition accuracy and speed of PACCI have been improved significantly.
