WORKING MACHINE AND METHOD OF CONTROLLING WORKING MACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18597979 titled 'WORKING MACHINE AND METHOD OF CONTROLLING WORKING MACHINE
Simplified Explanation:
The patent application describes a working machine with a hydraulic actuator to raise/lower a structure, a control valve, and a controller to move the structure to a target position. The controller can switch between two modes to control the flow rate of hydraulic fluid based on the position of the structure.
- The machine includes a hydraulic actuator and a control valve.
- The controller can switch between two modes to control the flow rate of hydraulic fluid.
- The controller adjusts the flow rate based on the position of the structure.
- The machine can move the structure to a target position accurately.
- The innovation allows for precise control of the hydraulic actuator.
Potential Applications:
This technology can be applied in various industries such as construction, manufacturing, and agriculture for precise positioning of structures or equipment.
Problems Solved:
This technology addresses the issue of accurately controlling the movement of structures using hydraulic actuators, ensuring precise positioning.
Benefits:
The benefits of this technology include improved accuracy in positioning structures, increased efficiency in operations, and reduced risk of errors in hydraulic actuator control.
Commercial Applications:
Potential commercial applications include automated machinery, robotic systems, and industrial equipment that require precise control of hydraulic actuators for positioning tasks.
Questions about the Technology: 1. How does the controller determine the flow rate of hydraulic fluid in each mode? 2. What are the safety features implemented in the machine to prevent accidents during operation?
Frequently Updated Research:
Researchers are continually exploring advancements in hydraulic control systems to enhance the efficiency and accuracy of industrial machinery.
Original Abstract Submitted
A working machine includes a driver including a hydraulic actuator and a driven structure to be raised/lowered by the hydraulic actuator, a control valve to control the hydraulic actuator, and a controller configured or programmed to control the control valve to move the driven structure to a target position. The controller is configured or programmed to switch between (i) a first mode in which the controller controls the control valve by performing a first control based on a target flow rate of hydraulic fluid to actuate the hydraulic actuator and a deviation of an actual position of the driven structure from a target value and (ii) a second mode in which the controller controls the control valve by performing a second control including controlling the target flow rate to be lower than the first control when the deviation is more than zero and less than a predetermined deviation.
