Abstract : this paper developed time domain integral constraints on error response for siso feedback control systems caused by nominal plant ' s near cancellation of stable pole - zero near the j - axis. these integral constraints should be satisfied by any feedback control systems. these integral constraints give new insight into the inherent trade - offs. it will result in the settling time longer or the infinite norm of the error response larger when there are near cancellations of stable pole - zero near the j - axis. hence, when feedback control systems are designed, it is necessary to avoid the compensator ' s poles and zeros nearly cancelling the nominal ' s zeros and poles ( even if these poles and zeros are stable )
文摘:導出了單輸入單輸出反饋控制系統誤差響應基於名義系統穩定的零、極點近似相消的時間域積分約束，此積分約束是任何反饋控制系統均應滿足的.這一約束給出了單輸入單輸出反饋系統固有折中的新的觀點.名義系統穩定的零、極點近似相消的存在導致反饋控制系統的調節時間延長或者誤差響應的無窮范數變大.因此，在反饋控制系統設計中，盡量避免補償器的零、極點與名義系統的極、零點近似相消（即使這些零、極點是穩定的） -

In the proposed technique the bemf waveform of bldcm need to be measured in advance at first, through computer simulation and frame transformation, the optimum q - axis current command is achieved. in order to minimize the torque ripple, the d and 0 - axis current command should be zero. furthermore, through reference frame transformation from dqo - axis to abc - axis, we can get the optimum current command in static abc reference frame
在這種控制方法中首先測量出電機的實際反電動勢波形，然後通過計算機擬合和坐標變換，求得產生恆定電磁轉矩所需的q軸電流，令i _ d ~ * = i _ 0 ~ * = 0 ，通過坐標變換，得到三相靜止坐標系a - b - c下的參考電流i _ a ~ * ， i _ b ~ * ， i _ c ~ * ，利用電流滯環控制來產生pwm信號，由於這種控制方法中電流不會突變，從而可以較好的抑制轉矩脈動。 -
