【摘要】 提出一种新的基于有限控制状态模型预测控制(FCS-MPC)的无刷直流电动机脉动抑制优化算法。该目标控制算法是根据系统有限个控制状态,由预测模型计算每种控制状态下被控量的预测值,并通过指标函数选择最优的控制状态施加于被控制对象,使关断相与开通相电流斜率近似相等,从而达到抑制换相转矩脉动的目的。仿真结果表明,该控制策略可以在全速范围内有效的解决转矩脉动问题,而且不需要准确计算换相时间,具有简单实用的特点。更多还原

【Abstract】 A new brushless motor ripple rejection optimization algorithm with finite control set model predictive control(FCS-MPC) was introduced.According to the system finite control set,the predictive value was calculated by predictive model,and the optimal control set was chosen to apply to control object,so that the slope of non-conduction phase current equaled to that of conduction phase current to reduce the torque ripple.Simulation results show that the proposed control strategy can effectively solve the problem of torque ripple of the full range without calculating commutation time,and has the characteristics of simple and practical.更多还原
