多模态控制系统可以根据系统运行状态,实时选用最合适的控制方法,实现多种控制策略优势的综合,使得系统的控制性能满足较高的要求。在多模态控制结构的设计中,模态的划分与各模态下的控制策略的选取直接影响多模态结构的控制效果。模态的划分取决于设计者对所应用的工业背景及复杂对象的深入了解与分析,而具体的控制方法则包括变增益控制、滑模控制、人工智能控制、基于多模型的控制。结合多个领域的研究现状,介绍上述各方法的特点与应用形式,对于设计一个实际的多模态控制系统具有借鉴意义。
Multi-modal control system can be based on the system operating conditions, real-time selection of the most appropriate control method to achieve a variety of integrated control strategy advantages, making the system’s control performance to meet the higher requirements. In the design of multi-modal control structure, the division of modal and the selection of control strategy in each modality have a direct impact on the control effect of multi-modal structure. Modal division depends on the designer of the applied industrial background and complex objects in-depth understanding and analysis, and specific control methods include variable gain control, sliding mode control, artificial intelligence control, based on multi-model control. Combining with the research status in many fields, this paper introduces the characteristics and application forms of the above methods, which is of reference significance for designing an actual multi-modal control system.
