Somatosensory Gimbal Control Using Angular Velocity Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for controlling gimbals using somatosensory controllers result in slow response times, making it difficult for the gimbal to follow attitude changes, thereby impacting control efficiency.
Innovation Solution
A method where the somatosensory controller receives angular velocity information, determines a target attitude for the gimbal, and transmits this information to control the gimbal's rotation axes, using a geodetic coordinate system and incorporating inertial measurement units and compasses for accurate data, with optional control modes for velocity and position control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional control methods are used to control the gimbal with a somatosensory controller, then the system structure remains simple, but the response speed is slow and the gimbal cannot follow attitude changes quickly
Solution Approach 1:
The patent replaces traditional position-based control with velocity-based control, where the gimbal directly responds to angular velocity information from the somatosensory controller. This substitution of control methodology enables the gimbal to track attitude changes more quickly by reacting to rate of change rather than position deviations, thereby improving response speed without requiring complex multi-sensor fusion systems.
Solution Approach 2:
The patent changes the control parameter from position/attitude to angular velocity. By transmitting and processing angular velocity information, the system enables dynamic response to user movements. The gimbal controller processes velocity data to continuously adjust the gimbal's attitude, achieving faster tracking performance through parameter transformation rather than increasing system complexity.
2Productivity
If the gimbal uses traditional control methods, then the control system remains simple, but the control efficiency is low
Solution Approach 1:
The patent substitutes traditional position control with velocity control, where angular velocity information directly drives gimbal movement. This replacement enables more efficient control by allowing the gimbal to anticipate and respond to user intent through velocity signals, reducing the time lag between user action and gimbal response, thereby improving control efficiency and reducing response time.
Solution Approach 2:
The patent implements preliminary action by having the gimbal system prepare for movement through velocity-based anticipation. The continuous monitoring and processing of angular velocity information allows the control system to initiate corrective actions before position deviations fully develop, improving control efficiency by acting in advance rather than reacting to errors after they occur.
