Positioning Control Settling Judgment via Segmented Error Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning control devices for disk devices face challenges in accurately and efficiently judging settling, as fixed slice and sample count conditions can lead to data erosion and poor positioning accuracy, making it difficult to balance speed and precision.
Innovation Solution
A settling judgment method that dynamically adjusts slice values and sample counts using multiple judgment formulas and blocks to compute position errors, allowing for flexible and accurate settling judgments, with the option to output OR or AND results based on different judgment criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high slice value and high sample count are used for settling judgment, then positioning accuracy is improved, but settling judgment time increases and response performance deteriorates
Solution Approach 1:
The patent divides the settling judgment into multiple independent judgment blocks, each with different slice values and sample counts. This segmentation allows parallel evaluation of multiple criteria simultaneously, achieving both high accuracy and fast response without increasing total judgment time.
Solution Approach 2:
The patent employs multiple judgment blocks with varying thresholds (some more stringent, some more lenient). This partial action approach allows the system to accept settling results from any block that meets its criteria, reducing the need to wait for all blocks to complete and thereby decreasing overall judgment time while maintaining accuracy.
2Device complexity
If fixed slice and sample count conditions are used, then device complexity is reduced, but data safety deteriorates due to potential data erosion
Solution Approach 1:
The patent segments the judgment conditions into multiple blocks with different slice values and sample counts. This segmentation provides diversified judgment criteria that adapt to varying operational conditions, preventing premature or incorrect settling judgments that could cause data erosion, while maintaining manageable system complexity through structured organization.
Solution Approach 2:
The patent changes the parameters (slice values and sample counts) across different judgment blocks to create a spectrum of judgment strictness. This parameter variation allows the system to adapt to different operational contexts, ensuring data safety by using appropriate judgment criteria for each situation without requiring overly complex configuration mechanisms.
3Productivity
If short settling judgment time is implemented, then response performance is improved, but positioning accuracy deteriorates due to missed residual vibration
Solution Approach 1:
The patent segments the settling judgment into multiple parallel blocks that can evaluate different aspects of positioning stability simultaneously. This allows the system to achieve fast response by accepting results from any block that detects sufficient settling, while maintaining accuracy through the diversified judgment criteria that capture residual vibration characteristics.
Solution Approach 2:
The patent implements continuous monitoring through multiple judgment blocks that operate simultaneously and continuously evaluate positioning status. This continuous action allows the system to detect settling conditions as they occur without delay, maintaining both fast response and high accuracy by not waiting for a single prolonged judgment process to complete.

AI summary
In a settling judgment method for judging whether an object is settled in a target position, the settlement is judged accurately at high-speed. In a positioning device for controlling a position of an object using a position error between a target position and a current position, a plurality of judgment blocks, each of which has a different judgment slice value and continuous sample count, are created in a settling judgment block for judging whether the object is settled within the positioning accuracy range of the target position, the judgment value of the position error computed by the judgment formula is judged in each judgment block each having a different judgment slice value and continuous sample count respectively, and OR of the judgment results is output. According to the settling judgment formula, settling can be judged accurately at high-speed, and both improvement of positioning accuracy and high-speed judgment can be implemented.
