Motor Control Parameter Tuning with Model Suitability Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor control systems face challenges in automatically adjusting control parameters efficiently, particularly when the control model is not suitable for simulation, leading to potential instability and prolonged adjustment times.
Innovation Solution
The motor control system employs a dual automatic adjustment method: one using a control model to adjust parameters when it is available, and another without the model when it is not, allowing for safe and efficient parameter setting through iterative processes based on detection values and threshold comparisons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automatic adjustment is performed using a control model, then adjustment speed is improved, but reliability deteriorates when the control model is not suitable for simulation
Solution Approach 1:
The patent introduces a model evaluation section as an intermediary that assesses the suitability of the control model before automatic adjustment is performed. This evaluation mechanism determines whether the control model is appropriate for simulation based on comparison values and threshold criteria, preventing unreliable adjustments while enabling fast model-based adjustment when conditions are suitable.
2Device complexity
If a single automatic adjustment method is used, then device complexity is reduced, but adaptability deteriorates when different adjustment scenarios are encountered
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the automatic adjustment method is selected based on real-time evaluation of control model suitability. The system transitions between different adjustment approaches (model-based when suitable, alternative method when not suitable) based on the output of the model evaluation section, providing adaptability without requiring a permanently complex multi-method structure.

AI summary
A motor control system includes circuitry configured to control a control object including a motor with a position detector, set a control parameter for controlling the control object, generate a control model representing a transfer function based on an operation command for generating the control model and an actual detection value detected by the position detector, and determine whether or not the control model is available for automatic adjustment of the control parameter. The circuitry is configured to adjust automatically the control parameter by a first automatic adjustment operation using the control model when it is determined that the control model is available for automatic adjustment, and to adjust automatically the control parameter by a second automatic adjustment operation without using the control model when it is determined that the control model is not available for automatic adjustment.
