High order Sliding control with High order observer applied on a bioreactor

The present paper provides a comparison between two different control strategies applied to a bioreactor system: A high-order sliding controller with a super-twist observer and a classic sliding control with a sliding observer. The performance of the two controllers is evaluated under different conditions, both with and without state perturbations, with a clear superiority for high order sliding control which eliminates chattering while maintaining performance. The results of this study are of great interest, as they offer insight into the efficacy of both control strategies in practical applications where the High Order Sliding Controller with the Super-Twist Observer provide an excellent response with an optimal control signal . Furthermore, the presented data demonstrates the response of the bioreactor system to the both controllers, providing valuable information for further research in this field.
