Engineering Contradiction Analysis
1Ease of operation
If manual adjustment method is used to commission control parameters, then the system can be configured, but the process is time-consuming and increases labor costs
Solution Approach 1:
The system performs self-commissioning by automatically identifying elastic modulus and torque parameters, and computing control parameters without requiring manual adjustment. The controller executes identification routines and calculations autonomously, allowing the system to configure itself and eliminate the need for operator intervention in parameter tuning.
2Ease of operation
If manual adjustment method is used to commission control parameters, then the system can be configured, but labor costs and downtime costs increase
Solution Approach 1:
The system performs self-commissioning by automatically identifying elastic modulus and torque parameters, and computing control parameters without requiring manual adjustment. The controller executes identification routines and calculations autonomously, allowing the system to configure itself and eliminate the need for operator intervention in parameter tuning.
3Device complexity
If simple control system is used, then the system is easy to implement, but good control performance is difficult to obtain
Solution Approach 1:
The system automatically identifies elastic modulus and torque parameters specific to the hydraulic system, then uses these identified parameters to compute optimal control parameters for the pressure controller. This adaptive parameter adjustment enables the controller to achieve superior performance by tailoring control characteristics to the actual system dynamics rather than using fixed or manually tuned parameters.
Solution Approach 2:
The system implements a feedback mechanism where the controller continuously monitors system performance and uses identified parameters to adjust control actions. The pressure controller receives feedback from pressure sensors and motor sensors, and automatically modifies control output based on the computed control parameters derived from elastic modulus and torque identification, enabling adaptive optimization of control performance.
