Non-Pharmacological Interventions for Covid-19 new Variants with Fractional Order Fuzzy Type-2 PID

Covid-19 disease has become a major challenge due to its high rate of transmission. All nations on earth were quickly infected by the virus. Recently, a novel viral variety with a substantially higher rate of transmission has been discovered. Vaccines and effective treatments are currently being developed and distributed, but in many nations, non-pharmacological interventions remain a crucial and basic tactic. One of the most vital global measures now involves concentrating on non-pharmacological means of stopping and reducing the transmission of the virus. In this work, a novel fractional order model of COVID-19 is used. The parameters in all variants of COVID-19 have uncertainty, so a novel robust Takagi-Sugeno (T-S) fuzzy type-2 fractional PID controller as a non-pharmacological intervention (NPI) is suggested in the presence of novel variations with a high rate of transmission to contain the illness outbreak in society. The proposed fractional controller has advantages such as robustness against new Covid-19 variations new Covid-19 variations with higher rate of transmission and, simplicity in design.
