A Novel Approach for Adaptive Partial Sliding Mode Controller Design and Tuning in Non-Minimum Phase Switch-Mode Power Supplies

In this article, a novel systematic approach is proposed for partial sliding mode controller (SMC) design and tuning in non-minimum phase switch-mode power supplies (SMPS). To achieve more simplified comparison with the conventional SMCs, SMC (PSMC) introduced which just requires part of surface formulation. The accuracy developed PSMC proved mathematically within entire range operation. Since control parameters are not selected by trial error, it can maintain stability robustness closed-loop system broad operational range. regard, to develop robust SMPS, constant frequency equivalent designed using converter nominal parameters. Then, extracted combined an adaptive component ensure asymptotical against load line changes. Considering Lyapunov criteria nonlinear systems, that presented SPMC be used output voltage regulation both discontinuous continuous operating modes zero steady state error. avoid error method during selection, characteristic equation Jacobian approach. roots stable system, tuned. Furthermore, addition simulation, evaluated practically TMS3220F2810 digital signal processor. It shown dynamic response faster than standard double-loop Additionally, seen model changes operations.
