The Research On IMC Method Of Multi-Delays And Non-Linear Multivariable Systems

Traditional controlling and identifying theories are mainly based on linear systems. As for non-linear systems, the identifying theories are poor and need developed. Now, the IMC theory on non-linear multi-varieties systems is the hot point and issue. In non-linear multivariable systems with pure time-delays, there also exists how to decouple the relations between circles. These problems bring difficulties to realize a rational and effective control system. This paper has researched on these problems by combining Fuzzy theory with IMC theory.This paper adopted a method combining IMC method and fuzzy control method to realize the IMC decoupling control on non-linear multi-varieties systems with time delays, meanwhile the control parameter can be adjusted on-line. And researches on model identification of multivariable system and how to apply fuzzy system theory in non-linear systems or multivariable systems were finished. The main researches include: Firstly, this paper discussed the IMC theory and its development, meanwhile proved the...
