... CTA exhibited high crystallinity, hydrophobicity, and excellent chemical, mechanical, and thermal resistance [6,7]. CTA was synthesized using a chemical reaction in acetic acid solvent between all groups of hydroxyl cellulose and carboxylic acid anhydride catalyzed by sulfuric acid [8,9]. CTA has been synthesized from a variety of primary sources, including recycled newspapers, cotton fibers, ramie fibers, empty palm oil waste, date palm seeds and eucalyptus pulp [10][11][12][13]. ...

... This brief proposes a solution to the above problem. A trajectory tracking controller who works with the system modeled in linear algebra equations [13]. ...

... Among the controllers utilized to face the difficulties in chemical processes the Sliding Mode Controller (SMC) has presented robustness against uncertainties, good performance for tracking and regulation, and is easy to implement [4]. Other control techniques, such as the based on numerical methods and linear algebra (LABC), presented good settling time and low overshoot, and good results for trajectory tracking [5]. However, it can give some drawbacks, such as a steady-state error and little robustness against disturbances if an integrator is not added to its control law. ...

... Over the past decades, the use of biochemical reactors and correlation techniques has increased greatly because of their fruitful application in converting biomass or cells into pharmaceutical or chemical products, such as vaccines [1], antibiotics [2], beverages [3], and industrial solvents [4]. Among various classes or operation regions of bioreactors, the fed-batch modes have extensively used in the biotechnological industry due to its considerable economic profits [5][6][7]. The main objective of these reactors is to achieve a given or maximum concentration of production at the end of the operation, which can be implemented by using some suitable feed rates [8][9][10]. ...
