  • 基于DSP28335+IR2110芯片的移相全橋驅動電路設計

    為解決移相全橋電路驅動及相角控制問題,設計了一種數字控制的移相全橋驅動電路.以TPL521為光耦隔離、IR2110為柵極驅動芯片.由DSP產生PWM信號,經過光耦隔離和邏輯電路后送至IR2110進行相角控制.文章對IR2110驅動電路原理進行分析及參數進行設計,對TMS320F28335進行設置并給出部分代碼.實驗結果表明:通過TMS320F28335可產生的不同相角的PWM波形,滿足了移相全橋對不同相角控制的要求.In order to solve the problem of phase-shifted full-bridge circuit driving and phase angle control,a digitally controlled phaseshifted full-bridge driving circuit was designed. TPL521 optocoupler isolation,IR2110 gate driver chip. PWM signals are generated by the DSP and sent to the IR2110 for phase angle control after optocoupler isolation and logic circuits. This text carries on the analysis to the principle of IR2110 drive circuit and parameter design,set up and give out some code to TMS320F28335. The experimental results show that the PWM waveforms with different phase angles generated by TMS320F28335 can meet the requirements of phase-shifted full-bridge control for different phase angles.

  • 基于滑模觀測器與分數階鎖相環的無傳感器PMSM矢量控制

    Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In this proposed FO-PLL, method, a regulable fractional order r is involved, which means that the FO-PLL provides an extra degree of freedom. In fact, the conventional phase-locked loop (PLL) applied in sensorless PMSM control can be seen as a special case of the proposed FO-PLL. By selecting a proper fractional order r a better performance may be achieved. The computer simulation results demonstrate the effectiveness of the proposed method.Key words: fractional calculus; fractional order phase-locked loop; sensorless control; sliding mode observer; permanent magnet synchronous motor; speed controll

  • 射頻鎖相環基礎理論

    一.基礎理論鎖相環路(Phase Locked Loop)是一個閉環的相位控制系統,它的輸出信號的相位能自動跟蹤輸入信號相位。系統框圖如下:當0,(1)與0:(1)相等時,兩矢量以相同的角速度旋轉,相對位置,即夾角維持不變,通常數值又較小,這就是環路的鎖定狀態。從輸入信號加到鎖相環路的輸入端開始,一直到環路達到鎖定的全過程,稱為捕獲過程。設系統最初進入同步狀態[2nrtto,e,.]的時間為1。。那么從1=1,的起始狀態到達進入同步狀態的全部過程就稱為鎖相環路的捕獲過程。捕獲過程所需的時間T,=1,-1,稱為捕獲時間。顯然,捕獲時間T,的大小不但與環路的參數有關,而且與起始狀態有關。對一定的環路來說,是否能通過捕獲而進入同步完全取決于起始頻差8.(4)-Ao。。若Ao,超過某一范圍,環路就不能捕獲了。這個范圍的大小是鎖相環路的一個重要性能指標,稱為環路的捕獲帶Ao,。
