5466-032 Woodward Ship Spare Parts

The 5466-032 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 5466-032
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 5466-032 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

For example, students who have worked on smart cars or similar devices should have a deep understanding.

The microcontroller outputs the same pulse width PWM to the motor, but with interference from factors such as power

supply voltage and wheel tightness, the actual output speed of the motor almost always changes.

How to solve this problem? Actually, we just need to change the input amount to the motor based on its actual speed.

For example, if we also hope that the motor can output 100 revolutions per minute under a load of 10 pounds, since the input to the

motor corresponds to an empty load of 100 revolutions per minute, and the actual output is only 80 revolutions per minute, we can consider

increasing the input to 120 revolutions per minute corresponding to an empty load. At this point, the actual output of the motor may be able to reach 100

revolutions per minute. Similarly, if the load continues to increase, we will further increase the input to control the actual output to remain at 100 revolutions per minute.

Most of Robomaster”s motors are equipped with Hall sensors that can provide feedback on speed/position information, so they can be controlled in a closed-loop manner.

Then let”s introduce what a typical feedback controller is (this model can be opened in Simulink in Matlab):

Generally, we subtract the measured output of the controlled object from our reference input to obtain an error value, which is then used as input to the controller.

The controller then outputs the result (control input) directly to the controlled object (plant).
