- 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
