Model predictive control (MPC) achieves very quick dynamic response with simple concept by selecting the best voltage vector minimizing the errors between the reference value and the feedback value. However, the steady state performance is still not satisfactory and it presents variable switching frequency. Introducing duty cycle control into MPC can improve the steady state performance but the control...
Due to the execution delay of the control signal caused by digital controller, there is one sampling time delay between the required optimal switching state and the executed switching state under the conventional model predictive controlled (MPC) systems, which lowers the system performance. In this paper, a two-step model predictive control (TS-MPC) strategy is proposed for a dual induction motor...
Since the amount of switching states is up to 32, if the conventional model predictive control (MPC) techniques is applied to the five-leg inverter, there are a huge calculation, which cannot be realized by using the modern digital signal processor. In this paper, a restrained search predictive control (RSPC) method is proposed. The limit of switching action times during the transactions between switch...
