4. Applications in Industrial Automation
The EASYGEN2500-5/P1 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.

3. Fully closed-loop control motion controller
By using detection elements such as gratings to detect the position of the controlled unit, transmission errors in the entire
mechanical transmission chain from the motor to the controlled unit can be eliminated, resulting in high static positioning accuracy. However,
due to the nonlinear friction characteristics, rigidity, and clearance of many mechanical transmission links within the entire control loop, and the
large dynamic response time (compared to electrical response time) of the entire mechanical transmission chain, it is difficult to calibrate the stability
of the entire closed-loop system, and the design and adjustment of the motion controller are also quite complex.
Motion controllers are classified based on the nature of the controlled variable and the motion control method:
1. Position control
The position control of the motion controller can be divided into point-to-point motion control and continuous trajectory motion control according to the control principle.
Point position control is a point-to-point positioning control that does not control the motion trajectory between points, nor does it perform processing or measurement during this process.
Continuous trajectory control is divided into linear control and contour control. Linear control refers to the linear motion of the controlled object in a certain
direction at a certain speed (single axis or multi axis linkage), during which processing or measurement is required; Contour control is the process
of controlling the instantaneous position and velocity of two or more coordinate axes to form a contour curve or surface in a plane or space through linkage.
