ISO 15746-1:2015 pdf free.Automation systems and integration – Integration of advanced process control and optimization capabilities for manufacturing systems
Process control is one of the most important branches of industrial automation. It aims at the control problems of process parameters, such as temperature and pressure. It covers a diversity of industrial fields, such as petroleum, chemicals, electric power, metals, textiles, building materials, light industry,nuclear energy, and pharmaceuticals.
With the development of modern industries, controlled objects are becoming increasingly sophisticated,which brings along with it new difficulties and challenges, such as multiple time varying parameters, large time delays, high nonlinearity, and complex coupling among input and output variables. Normal single loop control strategies can no longer achieve the desired objective of modern industrial automatic control.Since the 1970s, with the development of control theory and technology, a series of APC-O strategies have been proposed, such as multi-loop control and optimization strategy based on a system model, control strategy based on artificial intelligence and supervisory control strategy based on stochastic statistical analysis. The typical examples of APC-O include multivariable model predictive control, gain-based optimization, adaptive control, expert control and stochastic statistical process control.
The soft sensor module serves in the same function as a physical sensor, except that values are obtained from a mathematical model of the physical sensor using other known variables as inputs. The soft sensor consequently enhances variable monitoring by increasing sampling frequency and replacing inaccurate measurements. The soft sensor module collects input data, and its outputs serve as inputs of the modules of APC and optimization to replace the measurements that are obtained from laboratory analysis or online analyzers with long cycle times.
The APC module includes a broad range of techniques and methodologies implemented within industrial control systems. APC differs from regulatory loop control strategies and it is intended to generate better control performance. The APC module collects input data from all the other modules of APC-0 system.Its outputs serve as inputs of the regulatory control system in Level 2 and all the other modules in APC-O system except soft sensor module.ISO 15746-1 pdf free download.
