A Direct Synthesis based Sliding Mode Control of a Nonlinear Continuous Stirred Tank Reactor.

This work proposes a sliding mode controller (SMCL) design approach based on direct synthesis method for non-linear continuous stirred tank reactor (NCSTR). The SMCL parameters are derived based on (i) NCSTR model obtained by performing the closed loop test on the nonlinear differential equations of the NCSTR, (ii) direct synthesis approach and (iii) grasshopper optimization scheme. The performance of the suggested approach is assessed by performing the simulation on the nonlinear differential equation of the NCSTR. The results indicate that the suggested approach delivers satisfactory performance under nominal and noisy conditions with minimal efforts by the controller.
