GB/T 32854.1-2016 in English

Implementation Recommendations Chapter

1. Comparative Analysis of Standardization Frameworks

• Compare with enterprise control system integration standards such as GB/T20720.1 to identify differences and commonalities.
• Clear the functional hierarchy model of the manufacturing system (as shown in Figure 1) to ensure the effective implementation of control activities at the second layer.

2. Implementation Path of Functional Modules

• Soft Measurement Module: It is recommended to use partial least squares (PLS) and neural network technologies to solve the variable estimation problem. Example: Estimating the dominant variable through auxiliary variables in a petrochemical unit.
• Advanced control module: Prioritize the use of model predictive control (MPC) and fuzzy control strategies to achieve coordinated control of multivariable systems.
• Optimization module: Combine steady-state optimization and real-time optimization techniques to find the best operating point in the production process.
• Performance evaluation module: Use key performance indicators (KPIs) to comprehensively evaluate the control system to ensure its stability and economy. Example: Use PID performance evaluation tools to monitor the operating status of the control system.

3. Implementation suggestions

• Enterprises should focus on the coordinated development of software and hardware during implementation to ensure seamless integration between modules.
• It is recommended to refer to the application architecture example in Appendix A to build an application system that meets the needs of the enterprise.
• During the performance evaluation phase, it is recommended to use typical techniques such as partial least squares (PLS) and principal component analysis (PCA) to improve the evaluation accuracy.
