Output Feedback Sliding Mode Control for Continuous Stirred Tank Reactors

The continuous stirred tank reactor (CSTR) is representative of a typical class of chemical equipment where the dynamics is nonlinear. The problematic issues in control of a CSTR are the model uncertainties and external disturbances. Driven by these challenging problems coupled with the need for demanding levels of performance, this paper establishes the dynamic model of CSTR and then proposes an output feedback sliding mode control in light of the established model. The validity of the control algorithm and of the presented model are further verified by MATLAB simulation and experimental trials.
