多级耦合非线性系统的流控制
The flow control of nonlinear system with coupled multistage
摘要
Abstract
For a class of multistage-coupled and nonlinear system, whose dynamic characteristics follow the first and second laws of thermodynamics, for the high model dimension and coupling effects , it is difficult to realize the stable control for this class of system. Therefore, a flow control method is applied in this paper. This control method takes advantage of the relationship between system material flows and energy flows, to build a macroscopic thermodynamic model instead of a high dimensional microscopic model. In this way, a complicated system can be modeled in lower dimension. And this algorithm takes advantage that passive system is easy to control. It makes a system passive, so that makes it easy to realize a stable control for a complex multivariable system. In addition, it chooses system input or output flow as the manipulated variable, which realizes the easy operation in practice. In this paper, the multiple distillation as a typical example is used to prove the validity and effectiveness of flow control algorithm. The arithmetic steps is given, and all results shows that flow control algorithm can achieve satisfactory performance and have a good anti-interference ability.关键词
