| 摘 要： | 针对多电机同步系统具有强烈的非线性和耦合性，难以建立精确数学模型并施加有效控制的缺陷，提出一种多电机多模型动态矩阵预测控制算法．在辨识不同工况子模型的基础上，设计各自的子控制器，并利用加权和形式构造全局控制器，在有约束的条件下，通过滚动优化的策略获得合适的控制增量．控制过程中，无需进行磁链观测．仿真结果验证了该算法的有效性．

| Abstract: | For multi-motor synchronous system which is multivariable,strongly coupled,nonlinear,conventional controller based on non-precise system theories cannot meet the control requirements.Therefore,a kind of multiple model predictive control is designed.By identifying local models of different regimes,local dynamic matrix control(DMC)controllers are designed.Then the appropriate global controller is built by the weighting of the local controllers.Appropriate control increments are obtained by rolling horizon opt... |
