Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control parameters are manually adjusted through repetitive trial and error to accommodate varying mechanical parameters of load devices, then control stability can be achieved, but the time required for parameter setting increases significantly
Solution Approach 1:
The system automatically identifies evaluation index values for different load device states and orientations, calculates combined evaluation index values, and determines recommended control parameter values without requiring manual trial and error adjustment. The motor control device performs self-diagnosis and self-optimization by evaluating control performance across multiple orientations and situations, thereby achieving control stability while eliminating time-consuming manual parameter setting.
Solution Approach 2:
The system evaluates control performance across multiple orientations and situations by calculating evaluation index values for each state. Based on these evaluations, the system automatically determines optimal control parameter values that adapt to varying mechanical parameters of the load device. This parameter optimization process resolves the contradiction by finding the best parameter set that ensures control stability across all conditions without requiring repetitive manual adjustment.
2Productivity
If control parameters are optimized for one specific orientation or situation, then control performance is improved for that condition, but the system fails to maintain stability when the load device orientation or situation changes
Solution Approach 1:
The system evaluates control performance across multiple orientations and situations simultaneously by calculating evaluation index values for each state. The combined evaluation index value aggregates performance data from all orientations and situations, enabling the determination of control parameter values that universally optimize performance across diverse conditions. This multi-functional evaluation approach ensures that the system maintains both high control performance and adaptability to orientation changes.
Solution Approach 2:
The system extends the evaluation process from a single orientation to multiple dimensions by considering various orientations and situations. By calculating evaluation index values across this expanded parameter space and synthesizing them into combined evaluation index values, the system identifies control parameter values that perform optimally across all dimensional variations, thereby achieving both high performance and adaptability.

AI summary
A setting support device according to the present invention is provided with: a first identification means that identifies an evaluation index value indicating the stability or control performance of motor control by a motor control device in each of a plurality of load device states in which a load device is in mutually different orientations or situations; a second identification means that identifies, for each control device state, a combined evaluation index value representative of the evaluation index values in the plurality of load device states, identified for that control device state by the first identification means; and a recommended-value output means that identifies and outputs a recommended value of at least one control parameter on the basis of the combined evaluation index value identified for each control device state by the second identification means. This makes it possible to reduce the time needed for setting a parameter value in a motor control device that controls a motor that drives a load device in which a mechanical parameter changes depending on the orientation or situation.
