Abstract—In this paper, a simulated annealing algorithm tuned non-real-valued sliding surface is developed to enhance the transience and steady-state response of sine wave inverters. Even if the customary sliding surface (CSS) has the insensitivity to system uncertainties, the model of a reduced order exists in sliding action, thus yielding deficient system dynamics. By employing the non-real-valued sliding surface (NRVSS), the entire system dynamics can be established. Unfortunately, the occurrence of the chatter phenomenon is frequent and the harmonic distortion of sine wave inverter output is also high. To effectively reject the effect of the chatter, the NRVSS control gains can be optimally tuned via the simulated annealing algorithm (SAA). The proposed methodology has been implemented for the actual sine wave inverter controlled by a digital signal processor (DSP). Experimental results of the closed-loop system represent that the proposed methodology can provide fast transient response, low total harmonic distortion (THD) and the attenuation of steady-state error and chatter.
