考虑定位力矩补偿的磁通切换永磁电机模型预测转矩控制方法
A Model Predictive Torque Control Scheme for Flux-Switching Permanent Magnet Machines with Cogging Torque Compensation
摘要
Abstract
To alleviate the influence of the cogging torque,this paper develops a model predictive torque control (MPTC) scheme with cogging torque compensation for flux-switching permanent magnet (FSPM)machines.Firstly,the mathematical expression of the main harmonic components of cogging torque is obtained by finite element analysis.Then,according to the compensating control theory,a cogging-torque-compensating model is constructed to counteract the cogging torque.Further,based on the MPTC method,the cogging-torquecompensating model,the predictive torque model and the predictive flux model are employed to design the cost function.Both simulations and experiments verify that the developed control scheme not only compensates the cogging torque and suppresses the torque ripple,but also offers good dynamic performances.It should be emphasized that it is also applicable to conventional permanent magnet synchronous machines.关键词
