In this paper, a novel switching rule of DC-AC converter is proposed, which improves the static and dynamic performance of the system. Firstly, DC-AC converter is modeled as switched linear systems without any approximation, and the stable equilibrium fields and stable parameter fields of the switched linear systems are analyzed. And then the switching rule based on min-projection strategy is proposed, which utilizes the fact that the switched linear systems is stable if it is always possible to choose a vector field that points in a direction such that the trajectory converges to the desired equilibrium fields. Also, the switching rule parameters are designed by analyzing the THD, accuracy, robustness and dynamic response of the system under various loads such as resistor, and rectifier. Finally, experiments are performed to verify that the feasibility of the proposed switching rule with better dynamic response and strong robustness.

“…Much attention has been paid to regulation of the PWM inverter in order to ensure a sinusoidal waveform voltage with low THD, unchangeable frequency, and fast dynamic response under different types of loads [17]. The most known methods of regulation are the proportionalintegral-derivative (PID) control [18], sliding-mode control [19], linear control [20], Lyapunov control [21], linear resonant control [22], and passivity-based control [23]. Kalantar Zadeh et al presented in [24] a comparison between three types of controllers: sliding mode, back-stepping, and fuzzy logic.…”

We propose a high-performance and robust control of a transformerless, single-phase PV inverter in the standalone mode. First, modeling and design of a DC-DC boost converter using a nonlinear back-stepping control was presented. The proposed converter uses a reference voltage that is generated by the Perturb and Observe (P&O) algorithm in order to extract the maximum power point (MPP) by responding accurately to varying atmospheric conditions. Another goal for using the boost converter is to raise the voltage at the input of the inverter without using a transformer in this system, thus making the system more compact and less expensive. Secondly, the single-phase H-bridge inverter was controlled by using back-stepping control in order to eliminate the error between the output voltage of the inverter and the desired value, even if there is acute load variation at the output of the inverter. The stability of the boost converter and H-bridge inverter was validated by using Lyapunov’s stability theory. Simulation results show that the proposed PV system with back-stepping controllers has a good extraction of the MPP with an efficiency of 99.93% and 1 ms of response time. In addition, the sinusoidal form of the output voltage of the inverter is fixed to 220 V and the total harmonic distortion of the output voltage was found to be less than 1%.

Load uncertainties and harmonic disturbance are important issues in three-phase PWM inverter control. In this paper, a harmonic disturbance observer is developed to estimate the mismatched periodic disturbance which is produced by load uncertainty in the three-phase PWM inverter. Based on the estimation of disturbance, a special sliding-mode control (SMC) algorithm is designed to deal with the mismatched disturbance. The proposed harmonic disturbance observer can take advantages of the information of the periodic disturbance, thus the controller can obtain more accurate control signal for the inverter system. Simulation results show that the proposed method is able to attenuate the mismatched periodic disturbance and exhibits a better control performance.
