The goal of this project is to advance switching control theory and to develop competitive nonlinear control techniques. There are many switched systems emerging recently in engineering practices that involve interactions between continuous time and discrete event dynamics. Switched systems provide a useful mechanism to model complex dynamics that are subject to abrupt parameter variations and sudden changes in system configurations. Using multiple and conjugate Lyapunov functions, this effort will investigate new switching control techniques with different switching rules to improve controlled performance and expand control design capability. Another focus of the research is to generate computationally efficient algorithms tailored to an important class of non-convex problems arising from switching control designs. This research will make fundamental contributions by developing switching control schemes to handle modeling inaccuracy and actuator nonlinearity and generating effective computational tools from combined deterministic and probabilistic perspectives.The application of the projected switching control techniques and software tools to hypersonic aircraft could realize the full potential of ultrahigh speed aircraft flight, which has critical implications for both defense and commercial applications. The outcome of the research would have significant commercial, defense, and national security impacts. The success of this project can serve as a catalyst for the widespread use of theoretically sound and practically useful switching control approaches in engineering applications. The educational and outreach activities will enhance North Carolina State University's educational program by generating undergraduate research opportunities and facilitate university-industry collaboration and technology transfer.

本计画的目标是推进切换控制理论，发展具竞争力的非线性控制技术。近年来，工程实践中出现了许多涉及连续时间和离散事件动态之间相互作用的切换系统。切换系统提供了一种有用的机制来模拟复杂的动态，受到突然的参数变化和系统配置的突然变化。利用多重共轭李雅普诺夫函数，这项工作将探讨新的切换控制技术与不同的切换规则，以改善控制性能和扩大控制设计能力。研究的另一个重点是生成计算效率高的算法量身定制的一类重要的非凸问题所产生的开关控制设计。本研究将通过开发切换控制方案来处理建模不准确性和执行器非线性，并从确定性和概率的角度产生有效的计算工具，将投影切换控制技术和软件工具应用于高超声速飞机，可以实现高超声速飞机飞行的全部潜力，这对国防和商业应用都具有重要意义。研究结果将对商业、国防和国家安全产生重大影响。这个项目的成功可以作为一个催化剂，广泛使用的理论声音和实际有用的开关控制方法在工程应用中。教育和推广活动将通过创造本科生研究机会和促进大学-产业合作和技术转让来加强北卡罗来纳州州立大学的教育计划。
