CONTROL DEVICE FOR REDUCING A DELAY OF THE RELATIVE MOVEMENT OF THE VIBRATING BODY AND THE CONTACTING BODY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18595080 titled 'CONTROL DEVICE FOR REDUCING A DELAY OF THE RELATIVE MOVEMENT OF THE VIBRATING BODY AND THE CONTACTING BODY
Simplified Explanation:
This patent application describes a control device that manages the movement of a vibrating body and a contacting body in relation to each other through vibration. The device controls the phase difference between signals applied to an electromechanical energy conversion element to initiate the movement of the bodies.
- The control device adjusts the phase difference between signals to a specific value when the bodies are stationary and then initiates their relative movement.
- The phase difference is set to ensure that the initial relative position or speed of the bodies aligns with the desired position or speed.
Key Features and Innovation:
- Control device manages the movement of vibrating and contacting bodies through vibration.
- Adjusts phase difference between signals to control relative movement.
- Ensures alignment of initial relative position or speed with the target position or speed.
Potential Applications:
This technology could be used in:
- Vibration control systems
- Haptic feedback devices
- Precision positioning systems
Problems Solved:
- Ensures smooth and accurate movement of vibrating and contacting bodies.
- Prevents misalignment between initial and target positions or speeds.
Benefits:
- Improved precision in controlling relative movement.
- Enhanced performance of vibration actuator systems.
- Increased accuracy in positioning applications.
Commercial Applications:
Potential commercial uses include:
- Manufacturing automation
- Robotics
- Virtual reality systems

Original Abstract Submitted
A control device controls driving of a vibration actuator that moves a vibrating body and a contacting body in contact with the vibrating body relative to each other by vibration of the vibrating body excited when a plurality of signals having a phase difference are applied to an electromechanical energy conversion element. The control device includes a first control unit that controls the phase difference between the signals to a first phase difference when the vibrating body and the contacting body do not move relatively and starts moving the vibrating body and the contacting body relatively. The first phase difference is such that the positive/negative sign of the relative position or the relative speed of the vibrating body and the contacting body immediately after the vibrating body and the contacting body start moving relatively is not opposite to the positive/negative sign of the target position or the target speed.
