This paper proposes the instantaneous control method of a utillity interactive inverter with unknown R-L series load Sliding mode control and adaptive parameter estimation are applided to this by stern, which realizes following function. (1) synchronization of phase, frequency, and amplitude between inverter voltage and utility volltage at standalone mode (2) phase synchronization between inverter current and utilitj voltage at interactive-mode
Therefore, despite sudden increase in load current over setting point at stand-alone mode, inverter system can be transferred into parallel mode or interactive mode immediately without transient current. Load parameters, R and L, are estimated by using the recursive least aquare method and these parameters are used to adjust the feedback gains of control input
A DSP-based(TMS320C31) PWM inverter controller is implemented to verify the effectiveness of the proposed control scheme Simulation and experiment based on the second-order model are done and the results show good dynamic response according to each mode and low THD.
