据美国一机构(FIND/SVP)预测,到1999年先进控制技术产品的全球市场将增加到USS2.78×10~8,销售额增长64％。该调查公司研究考查了比例积分微分控制,模型预控制、人工智能技术(包括专家系统),模糊逻辑和中性网络等的目前市场情况。 模型预测状态控制正从炼油业发展到其它加工工业,第二种趋向是对非线性工艺过程模型的开发。 模糊逻辑很适合用于重大过程的失常和过程变量中的高可变性,由于这些方面已得到很好的应用,所以模糊逻辑产品的使用将更加广泛,中性网络的应用也是如此。 发展中国家的需求将引起过程控制设备销量的增长,根据RND/SVP公司的观点,建设一座发电厂、化学工厂或炼油厂需要以资本投资的5％到10％用于过程控制设备。在亚洲,控制产品的最强劲市场除日本外就是中国和印度。
According to a forecast by the United States agency (FIND/SVP), the global market for advanced control technology products will increase to USS 2.78×10~8 by 1999, and sales will increase by 64%. The survey company studied the current market conditions of proportional-integral-derivative control, model pre-control, artificial intelligence (including expert systems), fuzzy logic, and neutral networks. The model predictive state control is moving from the refining industry to other processing industries, and the second trend is the development of nonlinear process models. Fuzzy logic is well-suited for the variability in major processes and in process variables. Because these aspects have been well applied, the use of fuzzy logic products will become more widespread, as will the use of neutral networks. Demand from developing countries will lead to an increase in sales of process control equipment. According to RND/SVP, building a power plant, chemical plant or refinery requires 5% to 10% of capital investment for process control equipment. In Asia, the strongest market for controlling products is China and India except Japan.
