Fractional-Order Sliding Mode Controller Design for a Modified Quadruple Tank Process via Multi-Level Switching

sliding surface is altered with fractional order dynamics. It makes a Fractional-Order SMC (FrSMC) and is proposed for both finite time convergence and counteract to the uncertainties present in the system. The undesirable chattering effect is reduced by introducing a novel exponential Multi-Level Switching (MLS) technique in order to protect control valve. Simulation results show the efficacy of the proposed Multi-Level Switching FrSMC (MFrSMC) in terms of fast convergence with high robustness when compared to conventional SMC.
