摘要:
强制循环蒸发器是典型的多输入多输出强耦合非线性系统,常规的线性控制方法难以满足高性能控制的要求.在对强制循环蒸发器结构和工艺过程深入分析的基础上,建立了其非线性动态模型.然后采用逆系统方法设计了状态反馈控制器实现闭环系统的精确线性化和解耦.最后,对得到的伪线性化系统利用最优控制理论设计优化控制器.仿真结果表明:与传统PID控制器相比,提出的非线性控制策略能有效提高强制循环蒸发器的动态性能．
Abstract:
Forced-circulation evaporators (FCE) are typical muli-input multi-output strong coupling nonlinearsystems and the conventional linear system controller cannot guarantee the high performance of the system. Inthis paper,a nonlinear dynamic model was constructed based on the analysis of the construction and engineering process of FCEs. Then,with the inverse system method,a state feedback controller was proposed to real-ize the linearization and decoupling. Finally , for the obtained pseudolinear system,an optimal controller wasput forward. The simulation results showed that compared to the conventional PID controller,the proposednonlinear controller can effectively improve the dynamic performance of FCEs
