Abstract:
Systems related to controlling a DC/AC converter. A control system uses a nonlinear adaptive observer to estimate the state variables inverter current and converter voltage using a sensed grid current and a bus voltage as inputs. For non-observable points (such as when the duty cycle=0.5), the required information can be found from the DC bus voltage.
