Multi-Actuator Controller for Independent Effect Bandwidth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-actuator systems lack the ability to independently control the response bandwidth of each effect, such as roll, pitch, and yaw, which is necessary for applications where response requirements change significantly during operation.
Innovation Solution
A cooperative multi-actuator variable bandwidth controller system that uses a single controller to receive system commands, compute actuator motor controller commands, and incorporate knowledge of an allocation matrix and desired bandwidths to control the response bandwidth of each effect independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single controller controls multiple actuators in a cooperative scheme, then the system achieves coordinated control of multiple effects, but the system cannot independently control the response bandwidth of each effect
Solution Approach 1:
The controller is segmented into multiple independent control loops, with each loop responsible for controlling the bandwidth of a specific effect (roll, pitch, or yaw). This segmentation allows each control loop to independently adjust its bandwidth without affecting other effects, resolving the contradiction between coordinated control and independent bandwidth control.
Solution Approach 2:
The controller implements dynamic bandwidth adjustment by varying the proportional and derivative gain parameters in real-time based on operating conditions. This dynamic adaptation enables the system to optimize response bandwidth for each effect independently while maintaining coordinated control through the unified controller architecture.
2Use of energy by moving object
If conventional independent actuator control is used, then each actuator is easily controlled individually, but the system cannot achieve power savings through bandwidth modification
Solution Approach 1:
The controller modifies the bandwidth parameter of each control loop by adjusting proportional and derivative gain parameters based on operating conditions. This parameter change enables power savings by reducing bandwidth (and thus energy consumption) when full response speed is not required, while maintaining the ability to achieve high bandwidth when needed for maneuvering.
