FCS-MPC-Based Current Control of a Five-Phase Induction Motor
Pages 34 - 38
Abstract
The traditional vector control of five-phase induction motor contains multiple PI parameters to be set, and there is a voltage modulation link, resulting in complex control system structure. In this paper, model predictive current control is introduced to replace vector control to solve the above problems. The state equations of stator current and rotor flux are discretized to obtain the prediction model. In the predictive current controller, the 32 voltage vectors output by five-phase inverter are traversed and optimized to obtain the switching state of the optimal voltage vector. At the same time, in order to solve the influence of the five-phase induction motor harmonic current space, the cost function uses the weight factor to adjust the harmonic current term, to achieve harmonic current suppression. The simulation results show that the five-phase induction motor with the model predictive current control strategy has fast dynamic response speed and good control effect when switching mode.
