Solve irregular, infinite-dimensional, and asymmetric LQ control problems Standard LQ control theory breaks down when regularity assumptions fail, state dimensions become infinite, or controllers have asymmetric information or roles. Nonstandard Linear Quadratic Optimal Control identifies the root causes of these breakdowns and introduces decoupling-based methods for forward-backward difference/differential equations to resolve them across both discrete-time and continuous-time settings. The book develops FBDEs decoupling techniques that enable optimal feedback controller design and feedback stabilization. Coverage extends to irregular LQ control of deterministic and stochastic systems with additive and multiplicative noise, stochastic LQ control with input delay and state delay, infinite-dimensional LQ control of partial differential systems, decentralized LQ control with various asymmetric information structures, open-loop and closed-loop Stackelberg game LQ control, and applications in networked control and multi-agent systems. Each topic connects theoretical results directly to engineering applications including autonomous driving. Readers will also find: A proposed general method of decoupling FBDEs to address the difficulties encountered in analytical designController and stabilization conditions for different non-standard LQ control characterized by distinct self-developed Riccati-like equations Designed for professionals and researchers in control theory, systems engineering, and autonomous driving, this book serves as both a theoretical reference and a practical toolkit. Graduate students with grounding in algebra, probability, and classical LQ regulation will find the structured progression from fundamentals to advanced applications accessible.

This specially formulated collection features 3 reviews of current topics and key research in sweetpotato.The first chapter examines the origin and dispersal of sweetpotato, considers in vitro germplasm storage in sweetpotato genebanks, and looks at the importance of managing sweetpotato crop wild relatives (CWR). The chapter also considers the specific issues associated with sweetpotato germplasm, as well as the application of next-generation sequencing to sweetpotato and its CWR.The second chapter reviews the development and application of genetic transformation and trait improvement to sweetpotato, including the development of sweetpotato plants which are resistant to disease and abiotic stress, and sweetpotatoes with improved starch quality and higher anthocyanin content.The final chapter examines the nutritional contribution made by OFSP (orange-fleshed sweetpotato) in poor rural communities in Malawi, Ghana, Nigeria and Burkina Faso; sustainable breeding and seed systems; and effective commercialisation and marketing to benefit the communities concerned. This chapter includes detailed case studies from Ghana and Malawi.
