Abstract—An integral sliding mode control (ISMC) based on game-theoretic approach to effectuate the satisfactory performance under the large perturbations/strong nonlinearities is presented for UPS inverters. This proposed methodology provides a modified construction compared with the conventional SMC. The integral compensator is employed to eliminate the steady-state error for small error circumstance. The game-theoretic approach is introduced to design the proper sliding surface so that the system stability and speedy response can be gained. The combined methodology of the ISMC and game-theoretic approach can be well used in UPS inverter to carry out a high reliable performance, even under hard transient and steady-state conditions, such as sudden load changes and rectifier loads. An experimental exploration is given to support the theoretical considerations and simulation results.

Index Terms—Integral sliding mode control (ISMC), steady-state error, game-theoretic approach, speedy response, UPS inverter.
