▲技术参数说明：8273-140 2301D WOODWARD 2301D负载分担和速度控制模块

  新的2301D和2301D- ec软件将与所有现有的2301D / 2301D-ec控制或任何具有模拟负载共享的控制一起运行。PID设置会有一些差异，特别是增益、复位和致动器补偿。如果更换旧零件号，请将新零件号的增益，复位和致动器补偿保留在默认值以开始调谐过程。不要将旧设备的PID设置复制到新设备上。Manual 26288列出了各种引擎的一些设置。

新的PID算法和自适应速度传感滤波器

PID改变，使2301D能够更好地控制慢速和中速发动机。

速度传感器，因为它测量速度，只会发送一个输出到PID与一个新的速度只有当发动机转速已经实际改变。这有助于控制低速发动机。自适应速度传感器学习或适应齿轮齿，扭力和慢速射击频率中的任何异常。

·现在有三种选择速度感应方式的方式:

1用于中高速发动机。通常使用这种速度传感类型的MPU频率为100Q赫兹。及以上。MPU齿轮分为16个部分;因此，速度被感知和更新一次，每1/16的一个完整的引擎革命。

4.速度传感器每一个定时脉冲都能感应速度。该功能是专门设计的，以提供读数在低速。速度仅通过使用两个齿间时间间隔来计算。这个功能测量每颗牙齿之间的时间，并存储最近的两次测量结果。该块在每次执行块时对这两个测量值进行采样和平均，并使用平均值来计算速度。

5是专门设计的自适应转速传感滤波器。该滤波器将提供稳定的速度传感器读数;

-发动机中低转速。

-由发动机点火频率或各种发动机负荷引起的发动机扭转频率。

-齿轮跑出、齿轮齿形不规则或飞轮孔形不规则引起的MPU信号噪声。

●不同软件的PID设置之间没有相关性。

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.
