Abstract
In this paper, the state space model predictive control system design for inverter switching pulses to produce the desired three-phase UPS outputs. Very fast dynamics and the ability to evaluate different cost functions of the advantages of predictive controller in designed. Relations in the system suggest a need to control the amount of time given the uncertain times, reduce costs and improve reliability, flow sensor, is designed to replace the observer. The common observers such as Luenberger Observer in terms of design, sustainability and complexity associated with difficulties. In this paper a novel observer based on fourier series and instatntius power theory in which desired operations have been achived, is designed. The proposed observer does not set specific parameters only measure of output voltage and filter current, ability to observation the load current with excellent accuracy. The proposed observer, a simulated 220-volt three-phase UPS tested and the results will be compared with Luenberger common observer.
