Comparisons of FCS-MPC schemes and conventional PI-based methods for electrical drive systems

Model predictive control (MPC) has gained increasingly popularities in the field of power electronics and electrical drive systems. In MPC, the control objectives are evaluated in the cost function within a certain number of prediction horizon. Compared with conventional PI-based methods, MPC shows the merits of simple concept, straightforward implementation, fast dynamic response, flexible inclusion of constraints and ability to handle multi-objective nonlinear system. Finite control set MPC (FCS-MPC) is one of the common-used MPC schemes. In this work, the comparisons of FCS-MPC schemes and the conventional PI-based method, e.g., direct torque control (DTC) and fiel-doriented control (FOC) are carried out. It is validated that FCS-MPC methods achieves a better control performance at both the steady state and transient state.     «
