Fashionable real - time databases at the present time, pi and phd, provide some general data process functions, such as unit conversion, filter, and evolution
目前流行的實時數據庫系統,如osi公司的pi 、 honeywell公司的phd ,都提供常用數據處理過程,如量程轉換、濾波、開平方、超限處理等。 -
The methods for speed identification based on kalman filter and model reference adaptive system are deeply investigated in this thesis, a new pi adaptive method of speed identification based on mras is put forward
本文研究了基於卡爾曼濾波演算法的速度辨識法和基於異步電機模型的模型參考自適應法,針對模型參考自適應法提出了一種pi自適應速度辨識法。 -
The mixed control chip sg3525a combined with hardware pi controller generates the high - frequency pwm pulse for the first inverter. the digital control block tms320lf2407a mainly provides current preset for constant - current source through the outer filter, pwm pulse for the second inverter and drive signal for the high - frequency pulse power supply
其中變極性電源的一次逆變pwm信號由pwm發生晶元sg3525a ,配以外部硬體電路pi調節器產生;一次逆變閉環控制迴路的電流給定(配以外部濾波) 、二次逆變pwm驅動以及高頻脈沖電源的控制則由tms320lf2407a數字控制器實現。
