▲技術(shù)參數(shù)說明:8273-140 2301D WOODWARD 2301D負(fù)載分擔(dān)和速度控制模塊
新的2301D和2301D- ec軟件將與所有現(xiàn)有的2301D / 2301D-ec控制或任何具有模擬負(fù)載共享的控制一起運(yùn)行。PID設(shè)置會有一些差異,特別是增益、復(fù)位和致動器補(bǔ)償。如果更換舊零件號,請將新零件號的增益,復(fù)位和致動器補(bǔ)償保留在默認(rèn)值以開始調(diào)諧過程。不要將舊設(shè)備的PID設(shè)置復(fù)制到新設(shè)備上。Manual 26288列出了各種引擎的一些設(shè)置。
新的PID算法和自適應(yīng)速度傳感濾波器
PID改變,使2301D能夠更好地控制慢速和中速發(fā)動機(jī)。
速度傳感器,因為它測量速度,只會發(fā)送一個輸出到PID與一個新的速度只有當(dāng)發(fā)動機(jī)轉(zhuǎn)速已經(jīng)實際改變。這有助于控制低速發(fā)動機(jī)。自適應(yīng)速度傳感器學(xué)習(xí)或適應(yīng)齒輪齒,扭力和慢速射擊頻率中的任何異常。
·現(xiàn)在有三種選擇速度感應(yīng)方式的方式:
1用于中高速發(fā)動機(jī)。通常使用這種速度傳感類型的MPU頻率為100Q赫茲。及以上。MPU齒輪分為16個部分;因此,速度被感知和更新一次,每1/16的一個完整的引擎革命。
4.速度傳感器每一個定時脈沖都能感應(yīng)速度。該功能是專門設(shè)計的,以提供讀數(shù)在低速。速度僅通過使用兩個齒間時間間隔來計算。這個功能測量每顆牙齒之間的時間,并存儲最近的兩次測量結(jié)果。該塊在每次執(zhí)行塊時對這兩個測量值進(jìn)行采樣和平均,并使用平均值來計算速度。
5是專門設(shè)計的自適應(yīng)轉(zhuǎn)速傳感濾波器。該濾波器將提供穩(wěn)定的速度傳感器讀數(shù);
-發(fā)動機(jī)中低轉(zhuǎn)速。
-由發(fā)動機(jī)點(diǎn)火頻率或各種發(fā)動機(jī)負(fù)荷引起的發(fā)動機(jī)扭轉(zhuǎn)頻率。
-齒輪跑出、齒輪齒形不規(guī)則或飛輪孔形不規(guī)則引起的MPU信號噪聲。
●不同軟件的PID設(shè)置之間沒有相關(guān)性。

The new 2301D and 2301D-EC software will run with all existing 2301D-2301D-EC controls or any controls with analog load sharing. There will be some differences in PID Settings, especially gain, reset, and actuator compensation. If replacing the old part number, leave the gain, reset, and actuator compensation of the new part number at the default values to begin the tuning process. Do not copy the PID Settings of the old device to the new device. Manual 26288 lists some Settings for the various engines.
New PID algorithm and adaptive velocity sensing filter
The PID changes give the 2301D better control over slow and medium speed engines.
The speed sensor, as it measures speed, will only send an output to the PID with a new speed only if the engine speed has actually changed. This helps control the low-speed engine. Adaptive speed sensors learn or adapt to any anomalies in gear teeth, torque and slow fire frequencies.
· There are now three ways to choose the speed sensing mode:
1 For medium and high speed engines. The MPU frequency typically used for this type of speed sensing is 100Q Hertz. And above. The MPU gear is divided into 16 parts; As a result, speed is perceived and updated once, every 1/16 of a complete engine revolution.
4. Each timing pulse of the speed sensor can sense the speed. The feature is specifically designed to provide readings at low speeds. The speed is calculated only by using the time interval between the two teeth. This feature measures the time between each tooth and stores the results of the two most recent measurements. The block samples and averages these two measurements each time the block is executed, and uses the average to calculate the speed.
5 is a specially designed adaptive speed sensing filter. The filter will provide a stable speed sensor reading;
- Medium to low engine speed.
- Frequency of engine torsion caused by engine ignition frequency or various engine loads.
- MPU signal noise caused by gear running out, irregular gear tooth shape or irregular flywheel hole shape.
● There is no correlation between PID Settings of different software.
