Abstract:

This paper presents the current control of two level voltage source inverter (VSI) designed in a discretized model using model predictive control (MPC) technique. MPC basically deals with the minimization of cost function of the system. Cost function is a measure of error between the measured value and the reference taken. But if the sampling time of the discretized model is quite large then a delay will be observed during the application of the control technique. The delay compensation is done with the consideration of future reference value in the cost function formulation. The optimized voltage vector obtained by this method results in a output load current with reduced ripple content. The simulation results obtained without and with delay compensation are discussed.
