Abstract :
This paper presents a method of designing optimal dynamic compensator for a class of typical chemical reaction process-CSTR systems. Firstly, the model of nonlinear CSTR system is provided, Secondly, by using feedback linearization method, the nonlinear system is converted into a linear system, then according to the LQR theory, the methods of designing dynamic compensator is designed, and we analyze the asymptotic stability of the optimal regulator which has been compensated. At last, the simulation results show the effectiveness of the method.
