本文通过实验性的套管换热器的前馈——反馈控制系统试验及其电模拟,对应用常规仪表实现简单的前馈——反馈控制问題作了实验研究。文章介绍了前馈模型的简化与实施、前馈——反馈系统品质改善、前馈模型的工程整定方法以及前馈系统设计等有关问题。可供工业应用参考。所介绍之内容对应用计算机实现前渍控制同样可作参考。由于试验装置的局限性,所得结论难免带有片面性,有待今后工业装置的试验而逐步完善。
In this paper, experimental feedforward-feedback control system experiments and electrical simulation of the experimental casing heat exchanger were carried out, and the simple feedforward-feedback control problem with conventional instruments was studied experimentally. The paper introduces the simplification and implementation of feedforward model, the improvement of feedforward-feedback system, the engineering tuning method of feedforward model and the design of feedforward system. For industrial applications reference. The contents of the introduction of computer control before the implementation of stain control can also be used as a reference. Due to the limitations of the test equipment, the conclusions inevitably brought with one-sidedness, pending the gradual improvement of the test of industrial installations in the future.
