Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only frequency response simulation is performed, then the simulation device can display frequency response characteristics, but the control parameters of velocity controller and position controller cannot be adjusted
Solution Approach 1:
The simulation device is designed to perform multiple types of simulation simultaneously - both frequency response simulation and time response simulation. By integrating both simulation capabilities into a single system, the device can display both frequency response characteristics and time response characteristics, enabling comprehensive adjustment of control parameters including velocity controller and position controller parameters.
2Manufacturing precision
If actual operation method is used to adjust control parameters, then the control parameters can be set based on real device response, but the device must be operated repeatedly which consumes time
Solution Approach 1:
The simulation device performs preliminary simulation before actual device operation. By conducting both frequency response simulation and time response simulation in advance, users can predict the behavior of control parameters and make informed adjustments without repeatedly operating the actual device. This preliminary simulation action reduces the time required for parameter adjustment while maintaining accuracy.
Solution Approach 2:
The simulation device creates a virtual copy of the actual device's behavior through mathematical models. By copying the dynamic characteristics and response behaviors of the real device into a simulation environment, users can test and adjust control parameters on the virtual model, avoiding repeated actual device operation while maintaining the accuracy of parameter setting.
3Loss of information
If comprehensive simulation including both frequency and time response is implemented, then both types of response characteristics can be displayed, but the device complexity increases
Solution Approach 1:
The simulation device merges frequency response simulation and time response simulation into a unified system. By combining both simulation functions and their respective displays into a single integrated device, the system avoids the complexity of separate independent systems while preserving all necessary response characteristic information.
