3. Brand History
Woodward, Inc., founded in 1870 and headquartered in Fort Collins, Colorado, USA, is a global leader in energy control systems. The company has a long history of innovation in turbine control, engine management,
and power generation systems.
Woodward products are widely recognized for their reliability and precision in demanding industrial and power generation applications.
4. Applications in Industrial Automation
The 8280-305 plays a critical role in industrial automation and power generation environments:
- Steam Turbine Control: Manages startup, speed regulation, and extraction/admission control of steam turbines.
- Power Generation Systems: Used in power plants to regulate turbine-driven generators for stable frequency and load management.
- Compressor and Pump Drive Control: Ensures precise speed control for turbine-driven compressors and pumps.
- Process Industry Applications: Applied in chemical plants, refineries, and other industries requiring precise turbine operation.
- Safety and Protection Functions: Includes overspeed protection, critical speed avoidance, actuator travel limits, and event logging for operational safety.
2. Speed control and acceleration control
The motion controller speed control can be used alone or combined with position control to form a dual loop control,
but the main loop is position control, and speed control serves as feedback correction to improve the dynamic performance of the system.
3. Synchronous control
Synchronous control of motion controller refers to the synchronous motion control of speed or position of two or more axes,
such as system control with electronic gearbox and electronic cam functions. Some require not only simultaneous startup,
but also position synchronization, which requires high synchronization accuracy.
4. Force and torque control
The coiler for plastic film, steel strip, cloth, and paper is controlled by constant tension. In situations such as tightening nuts and
automatic drilling of automatic assembly machines, the motion controller should adopt synchronous control of torque and position.
Composition architecture of motion control system
A motion controller is used to generate trajectory points (expected output) and a closed position feedback loop. Many controllers can also close a speed loop internally.
