Control Strategies for Non-minimum Phase Systems

This book provides overview of numerous control schemes for non-minimum phase and dead-time systems.  The inverse response arises from the conflict of two first-order systems with opposite effects. This feature of the system is known as non-minim phase (NMP) process. The opposite response initiates from odd multiplicity of NMP open-loop zeros. As a result, the controller shows a limited gain margin and bandwidth, implying a robustness restriction. If the user tries to increase the gain, system sometimes gets unstable. Thus, the fundamental notion of providing a suitable balance control theory can potentially improve the performance of those processes.  This book is useful to researchers working in the field of control system. The book provides comprehensive philosophy of different control schemes used for the non-minimum phase zeros and dead-time systems. The researcher working on non-minimum phase zeros can find innovative algorithms and novel schemes. Further, they can design innovative control schemes by referring to the content of chapters and specifically tuning after encountering NMP zeros and delay terms.
