【 摘 要 】

In this paper, a single sampling multi controlling-model predicted control (SSMC-MPC) scheme is proposed to decrease a considerable part of the computational burden and reduce the dependence on the sampling module. The SSMC-MPC achieves a ratio of control frequency to sampling frequency of N (N∈Z). The same control frequency requires only a lower sampling frequency module, which saves hardware costs and has advantages in practical application. By comparing the control effect of traditional FCS-MPC algorithm and SSMC-MPC algorithm, the proposed method and benefits were validated by simulations in MATLAB/Simulink.
