Abstract Model predictive control (MPC) is an advanced method of process control that has been enormously used in industry. In recent years, there has been a rapid increase in the use of digital controllers in control systems. The control of inverters with output LC filter has a special importance in applications where the high quality voltage is needed. Several control schemes have been proposed for the control of three - phase inverter. This thesis presents a new and simple control scheme using predictive control and implementing the proposed MPC on the eZdsp F28335 kit. The controller uses a discrete-time model of the system to predict the behavior of the output voltage for all possible switching states generated by the inverter. Then, a cost function is used as a criterion for selecting the switching state that will be applied during the next sampling interval. There is no need of internal current control loops and no modulators because the gate - drive signals are generated directly by the controller |
