Sliding-Mode Controller Based on Fractional Order Calculus for Chemical Processes

Abstract:

This study uses a fractional FOPDT model of the actual process to create a fractional sliding mode controller. Nonlinear chemical processes may be studied using the new methodology. The real chemical systems are described and represented by the controller design using the power of fractional order calculus as a reduced order model. From this model, the controller is developed using the sliding mode control process. An SMC based on FOPDT and the new method are compared using a higher order plus deadtime model. Lastly, some performance indicators are used to evaluate performance and robustness quantitatively.
