摘要
针对催化剂实验装置温度控制系统多变量、强耦合、大滞后的特点,提出一种基于传递函数伴随矩阵解耦基础上的预测控制。根据对象的伴随矩阵设计前馈解耦器,通过对解耦后对象的幅频和相频特性分析,获得具有相同稳态增益和幅值裕度的简化一阶数学模型,针对简化后的解耦系统设计预测控制器.通过仿真,结果表明方案有效。
The catalyst experimental device temperature control system is typically multi-variable strong coupled and large delay. Predictive control based on the decouple method using the adjoint matrix is proposed. The decoupler is designed based on the adjoint matrix of the multivariable system model with time-delay. By analyzing the amplitude-frequency and phasefrequency characteristics of the decoupled model, the decoupled model is reduced to a first-order model with time-delay.Predictive functional controller is constructed for the reduced model. Through the simulation, the results show that the method is effective.
