Comparison of backstepping, sliding mode and PID regulators for a voltage inverter

<p><span>In the present paper, an efficient and performant nonlinear regulator is designed for control of pulse width modulation (PWM) voltage inverter that can be used in a standalone photovoltaic microgrid. The main objective our to produce sinusoidal output signal with amplitude frequency are fixed by reference different loads including linear or types. A comparative performance study controllers based on non-linear techniques such as backstepping, sliding mode, proportional integral derivative (PID) developed ensure best choice among these three types controllers. system investigated compared under various operating conditions simulations MATLAB/Simulink environment demonstrate effectiveness methods. Our investigation shows backstepping controller give better than mode PID accuracy efficiency proposed verified experimentally terms tracking objectives.</span></p>
