Adaptive Finite-Time Tracking Control for Continuous Stirred Tank Reactor With Time-Varying Output Constraint

This article proposes an adaptive finite-time control plan for a nonlinear uncertain continuous stirred tank reactor (CSTR) with time-varying output constraint. The challenge in designing this control plan is how to achieve that system output never exceeding the specified time-varying compact as well as achieves finite-time convergence. By introducing the mean value theorem, the considered CSTR is decomposed to nonlinear systems (NSs) with pure-feedback structure. To deal with time-varying output constraint, tangent barrier Lyapunov function (TBLF) is applied in the adaptive finite-time controller design process. The closed-loop system stability can be identified by the presented adaptive finite-time control approach with the TBLF. Finally, the simulation graphics on CSTR are given to indicate the validity of the presented control approach.
