本文提出了一种基于嵌套优化策略和保成本控制的电机驱动系统控控一体化设计策略。由于对象设计与控制器设计之间存在耦合，传统的序贯设计方法无法保证被控电机驱动系统的整体最优性。本文提出的集成设计策略旨在通过同时优化控制器设计和装置设计来解决这一问题。综合设计的目标是驱动最大的负载，并保证在参数不确定的情况下参考跟踪具有满意的鲁棒控制性能。这可以通过将保证成本控制器集成到集成设计策略中来实现，并提高控制方案的可靠性。提出了一种包含对象设计目标和控制性能的新型组合性能指标作为电机驱动系统的综合设计成本函数。采用嵌套优化策略，有效可靠地计算出系统的最优性。实验结果证明了所提出的综合设计方法的有效性。
In this article, a plant/controller integrated design strategy based on the nested optimization strategy and guaranteed cost control for a motor driving system is developed. Because of the coupling between the plant design and the controller design, the conventional sequential design methods cannot guarantee an overall optimality for the controlled motor driving system. The integrated design strategy proposed in this article aims to tackle this problem by simultaneously optimizing the controller design and plant design. The integrated design objective is to drive the largest load and guarantee the satisfactory robust control performance for reference tracking subject to parametric uncertainties. This is enabled by integrating a guaranteed cost controller into the integrated design strategy and improves the reliability of the control scheme. A novel combined performance index including the plant design objective and the control performance is developed as the integrated design cost function for the motor driving system. A nested optimization strategy is employed so that the optimality of the system can be calculated in an efficient and reliable way. Experimental results demonstrate the effectiveness of the proposed integrated design method.
