For improving reliability of the fully electric armored wheel hub motor drive system and in view of the problem of dependence of classical finite-control-set model predictive control algorithm on motor parameters and additional excitation

a kind of an adaptive improved control algorithm independence parameter is proposed.All unmolded interference factors are converted into equivalent total errors so to ach ieve the adaptive predictive control

ease the algorithm’s dependence on parameter through online estimation of the equivalent total error and total inductance

and achieve position observer by the use of inherent current ripple excitation and avoid unfavorable influence due to input of extra high frequency signal.It is shown by the experimental result that the proposed algorithm can accurately estimate the rotor position and initial magnetic pole under different working conditions and loads of the motor

the control performance is still obtained without relying on the motor parameters and the effectiveness of the proposed algorithm is verified.
