sentences: This paper presents a filter-based control scheme for an H-Bridge inverter with output LC filter. This approach relies only on a single output voltage measurement to reduce the system cost as well as measurement noise and disturbance injected by output current and/or inductor current measurements. To reduce the controller sensitivity to the system parameters, the proposed controller is developed for unknown system parameters. A Lyapunov stability analysis is utilized to demonstrate system stability. Experimental results demonstrate excellent voltage regulation, insensitivity to load variations, and low output voltage distortion as well as the stability of the system under both linear and nonlinear loads.
