AI Technical Summary

Benefits of technology

The present technology describes how to improve the performance of electronic devices by reducing interference between moving parts caused during operation without causing damage. It involves detecting over-current instructions and adjusting certain parameters based on their impacts instead of just giving them upward. This helps reduce collisions and breaks down components more efficiently than traditional methods. Additionally, this system uses advanced techniques to rewrite signals before they reach us, further improving its efficiency. Overall, these technical improvements help make sure things work properly even if there're too much power usage compared to what was previously needed.

Problems solved by technology

This patents describes different techniques aim at reducing collisional damage caused when two moving parts come into contact during use of an electronic control system called an electro-magnetic valve. These methods include restricting power supply signals supplied to certain components while avoiding excessive force due to impact between these movements. Additionally, they involve monitoring and detecting any changes made over time without interrupting normal operations. However, existing solutions have limitations: limited protection against accidental failures; limitation of applying corrective currents only if necessary but cannot guarantee complete safety measures.

Abstract

A vibration damping apparatus including reference wave production section that produces a reference wave; a fundamental order adaptive algorithm block that calculates fundamental order adaptive filter factors from a vibration detection signal and the reference wave and produces a fundamental order vibration damping current instruction; an amplitude detection section that calculates a peak current value of the fundamental order vibration damping current instruction; and a fundamental order current excess detection section that derives a fundamental order current upper limit value from the fundamental frequency to produce a fundamental order current upper limit excess signal that is output to the fundamental order adaptive algorithm block, which revises the fundamental order adaptive filter factors in a direction in which the vibration damping current instruction is limited within a range.
