Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of sensors and actuators is increased to improve control system performance, then the control capability is enhanced, but the network response performance deteriorates
Solution Approach 1:
The network is divided into multiple communication channels, each handling specific sensor/actuator groups. This segmentation allows parallel communication streams that maintain response performance while supporting more devices. The central communication unit distributes data across multiple channels rather than using a single congested path.
Solution Approach 2:
The patent introduces a new dimension for data transmission by creating multiple communication channels (dimensions) instead of relying on a single communication path. This multi-dimensional approach allows simultaneous data flow through different channels, effectively increasing network capacity and response speed without adding physical infrastructure complexity.
2Adaptability or versatility
If the number of sensors and actuators is increased to improve control capability, then the control scope is expanded, but the adjustment and setup steps increase
Solution Approach 1:
The communication control setup computation section automatically generates communication control setups based on transmission characteristics without requiring manual configuration. The system performs self-testing and self-configuration, eliminating the need for operators to manually adjust communication parameters when adding sensors or actuators.
Solution Approach 2:
The system pre-computes communication control setups by evaluating transmission characteristics before actual operation. By performing preliminary analysis of the network topology and device characteristics, the system prepares optimal communication parameters in advance, so that when new devices are added, the setup is already determined and requires no manual intervention.
3Speed
If manual communication control setup is used to maintain network performance, then the response performance can be optimized, but the complexity of the system increases
Solution Approach 1:
The patent replaces manual mechanical configuration processes with automated computational methods. Instead of operators physically adjusting communication parameters, a computation section automatically determines optimal settings based on transmission characteristics, eliminating the need for complex manual setup procedures while maintaining optimized performance.

AI summary
A distributed control system and a control method for the distributed control system are provided that reduce adjustment and setup steps required when the system are applied to a control using sensors and actuators. The distributed control system includes a central communication unit and terminal communication units, the central communication unit and the terminal communication units connected to each other through a network. Communication control setup is automatically performed for each of the terminal communication units when control is exercised by using sensors and actuators connected to the terminal communication units based on each transmission characteristic of the time when a physical quantity generated by driving each of the actuators propagates to each of the sensors and on the setup of required performance of control.
