Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor control systems face challenges in setting optimal values for multiple control parameters, particularly when changing one parameter affects others, as they often limit simulations to two parameters, making it difficult to achieve appropriate settings for improved controllability.
Innovation Solution
A setting support device that allows for the simulation of multiple test actions by changing values of control parameters, with a parameter adjustment part that sets whether secondary parameters change along with primary ones, and a performance index calculation part that correlates performance indexes with primary control parameters, displayed through relational graphs to facilitate optimal setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only two control parameters are simulated, then the simulation complexity is reduced, but it becomes difficult to set multiple control parameters as appropriate values when one parameter change affects others
Solution Approach 1:
The patent transitions from 2D parameter simulation to 3D parameter space simulation by adding a vertical axis representing the third control parameter. This dimensional expansion allows simultaneous visualization and optimization of three parameters (e.g., position proportional gain, speed proportional gain, speed integral gain) while maintaining intuitive graphical interface, thus resolving the contradiction between simulation complexity and parameter setting capability.
2Adaptability or versatility
If multiple control parameters are changed simultaneously, then the optimal setting for multiple parameters can be achieved, but the processing time increases due to real machine measurement requirements
Solution Approach 1:
The patent creates a virtual copy (simulation model) of the motor control system that replicates real-world behavior without requiring physical machine measurement. This simulation environment allows multiple control parameters to be changed and evaluated simultaneously, achieving comprehensive parameter optimization while eliminating the time-consuming iterative measurement process required by prior art.
3Manufacturing precision
If comprehensive simulation of multiple parameters is performed, then appropriate control parameter settings can be achieved, but the system complexity and computational requirements increase
Solution Approach 1:
The patent introduces a graphical user interface as an intermediary between the complex simulation engine and the user. This interface simplifies the interaction by providing intuitive visual displays of three-dimensional parameter relationships, allowing users to comprehend and adjust multiple control parameters without being overwhelmed by the underlying computational complexity.
