This paper presents an adaptive terminal sliding mode control (ATSMC) strategy for DC-DC buck converters. The idea behind this strategy is to use the terminal sliding mode control (TSMC) approach to assure finite time convergence of the output voltage error to the equilibrium point and integrate an adaptive law to the TSMC strategy so as to achieve a(More)
A new approach to the sliding-mode control of single-phase uninterruptible-power-supply inverters is introduced in continuous time. A three-level hysteresis sliding function is used to directly control the inverter switches, with the result that a transistor is switched during a half-cycle while it remains either on or off during the other cycle. An(More)
This paper presents a sliding mode control (SMC) strategy for single-phase grid-connected LCL-filtered voltage source inverters (VSI) with double-band hysteresis scheme. The proposed SMC is simpler than the existing SMC methods devised for grid-connected VSI since its sliding surface function requires the sensing of capacitor voltage and grid current only.(More)
An optimal control strategy based on the linear quadratic regulator approach is proposed for single-phase uninterruptible power supplies in continuous time. The objective of the controller is to achieve a fast transient response, good voltage regulation, and low total harmonic distortion of the output voltage under linear and nonlinear loads. It is shown(More)
