项目摘要

In order to satisfy the increasingly enhanced requirements for system performance, practical engineering systems are now frequently modelled as complex interconnected systems. The study of such classes of systems is both challenging and adventurous due to the presence of nonlinearity, interconnections between subsystems, time delay and uncertainty between such models and the real world. The research described in this proposal aims to develop a novel design approach and to provide practical but rigorous solutions to the problems of decentralised observer and controller design for complex interconnected systems using HOSM techniques. The project will strengthen the collaboration between two leading sliding mode research teams to create a framework for this new research area. In order to avoid packet problems with transfer of information between subsystems, decentralised strategies will be the focus of this research. A novel approach involving artificial interconnections will be developed to reduce the conservatism caused by interaction between subsystems when decentralised strategies are employed. One specific focus will be to remove/suppress the undesired chattering to improve closed-loop system performance. The investigator has been heavily involved in research on interconnected systems using classical sliding mode control for over 10 years and has a strong research track record. The project partner has obtained excellent results in HOSM control specifically in chattering suppression, which is internationally leading in the area of HOSM. The expertise of both research teams is considerable and complementary. The experimental equipment provided by the projector partner will be crucial for testing the results obtained. All these factors are very important to guarantee the project success. As the focus of this proposal is to remove chattering whilst preserving the advantages of HOSM techniques and decentralised strategies, this research will bring the advantages of high robustness to uncertainty, ease of implementation, high reliability and increased lifespan of moving mechanical components when implemented in real systems. The research has great potential to enhance economic efficiency.

为了满足日益提高的对系统性能的要求，实际工程系统经常被建模为复杂的互联系统。这类系统的研究具有挑战性和冒险性，因为存在非线性、子系统之间的相互关联、时滞和模型与现实世界之间的不确定性。这项研究的目的是开发一种新的设计方法，并利用HOSM技术为复杂关联系统的分散观测器和控制器设计问题提供实用而严格的解决方案。该项目将加强两个领先的滑模研究团队之间的合作，为这一新的研究领域建立一个框架。为了避免子系统之间的信息传输出现分组问题，分散策略将是本研究的重点。当采用分散策略时，将开发一种新的方法，包括人工互联，以减少由于子系统之间的相互作用而引起的保守性。一个具体的焦点将是消除/抑制不需要的抖动，以提高闭环系统的性能。这位研究员10多年来一直致力于使用经典滑模控制的互联系统的研究，并有很好的研究记录。项目合作伙伴在HOSM控制方面取得了良好的效果，特别是在抑制抖振方面，这在HOSM领域处于国际领先地位。两个研究团队的专业知识都相当丰富，互补性很强。投影机合作伙伴提供的实验设备将是检验所获得结果的关键。所有这些因素都是保证项目成功的重要因素。由于该方案的重点是在保持HOSM技术和分散策略的优点的同时消除抖振，因此该研究将带来在实际系统中实现的移动机械部件具有对不确定性的高度稳健性、易于实现、高可靠性和延长寿命的优点。该研究对提高经济效益具有很大的潜力。
