This book shows readers new ways to compensate for disturbances in control systems prolonging the intervals between time-consuming and/or expensive fault diagnosis procedures, keeping them up to date in the increasingly important field of adaptive control.

Computational Fluid Dynamics has now grown into a multidisciplinary activity with considerable industrial applications. The papers in this volume bring out the current status and future trends in CFD very effectively. They cover numerical techniques for solving Euler and Navier-Stokes equations and other models of fluid flow, along with a number of papers on applications. Besides the 88 contributed papers by research workers from all over the world, the book also includes 6 invited lectures from distinguished scientists and engineers.

Addressing the difficult problem of controlling flexible spacecraft having multiple articulated appendages is the aim of this volume. Such systems are needed for space mission concepts including multi-payload space platforms and autonomous space-based manipulators. These systems are characterised by highly nonlinear dynamics, flexibility in members and joints, low inherent damping, and modeling uncertainty. A complete nonlinear rotational dynamic model of a generic multibody flexible system is derived, and is shown to possess certain passivity properties. The main result is a class of passivity-based nonlinear and linear output feedback control laws that enable globally stable closed-loop manoeuvres. The control laws are robust to parametric uncertainties, unmodeled uncertainties, and in some cases, actuator and sensor nonlinearities. All results given are also applicable to flexible terrestrial manipulators.

This book is a research monograph that addresses the basic issues in controlling large, flexible space structures (LFSS), and presents some controller synthesis methods developed by the author. The main problem considered is that of controller synthesis for precision attitude control and vibration suppression in LFSS. The bulk of the book presents two basic approaches for controller synthesis: 1. a class of "dissipative" controllers which utilize collocated actuators and sensors, and 2. a class of model-based compensators. The book will serve to stimulate research activity in control theory with application to LFSS, and will be very useful to researchers, practising engineers, academic faculty, and students in control and aerospace sciences. The background required of the reader is familiarity with basic control theory including state variable methods, which is generally attained at the first-year postgraduate level.

The book "Compatibility of Trichogramma Chilonis Ishii with chemical pesticides: Integration of biological and chemical control" presents useful information on comparative safety of various chemical pesticides and biopesticides to Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae), a potent egg parasitoid of Lepidopteran pests, based on laboratory assessments. It is of practical significance in undertaking integrated pest management programmes with inclusion of biological control agents along with the other pest control methods. This book would be a very useful guide for students, plant protection scientists, extension workers and the entrepreneurs in different ways for getting insight into the intricacies of the issue and the options available for management
