摘 要: | 针对炉窑温度系统的大时滞、多扰动和非线性的特点,将T-S模糊状态空间模型作为预测控制的预测模型,并将T-S模糊表示的非线性系统转化为线性时变系统,给出了基于状态空间的多变量复杂系统的T-S模糊模型表达形式,设计出预测时域内多模型的非线性模糊预测控制器。根据实际控制中对控制量和输出的约束,将控制器输出求解转化为二次规划问题。

Abstract: | Accord to the features with big time-lag,disturbances and non-linear of the kiln temperature systems,this paper used the T-S fuzz state space model for the predictive control model,turned the non-linear system showed as T-S model to the linear timevarying system,made the multivariate complex system based on the state space,designed a nonlinear fuzz predicting controller during the predictive time domain.Under the constrains of controlled variable and outputs in the real system,translating the outputs solving r into a quadratic programming. |
