A tensile structure is a construction of elements carrying only tension and no compression or bending. The term tensile should not be confused with tensegrity, which is a structural form with both tension and compression elements. Most tensile structures are supported by some form of compression or bending elements, such as masts compression rings or beams. Tensile membrane structures are most often used as roofs as they can economically and attractively span large distances. Conventional structures rely upon two main principles, gravity and internal rigidity to achieve stability and carry loads. Tensile fabric architecture uses neither of these principles; instead a flexible, lightweight fabric membrane is stretched between a fixed set of support points. These structures, consisting of elements that have little or no stiffness, rely on their form and internal tension alone to carry their loads. As structural elements, tensile members are more efficient than compression members. Unless they have a certain minimal thickness, compression members will bend out of shape and fail regardless of their material strength. Structures made of tensile members are more stable.

The scope of the book covers most of the aspects as a primer on power electronics starting from a simple diode bridge to a DC-DC convertor using PWM control. The thyristor-bridge and the mechanism of designing a closed loop system are discussed in chapter one, two and three. The concepts are applied in the fourth chapter as a case study for buck converter which uses MOSFETs as switching devices and the closed loop system is elaborated in the fifth chapter. Chapter six is focused on the embedded system basics and the implementation of controls in the digital domain. Chapter seven is a case study of application of an embedded control system for a DC motor. With this book, the reader will find it easy to work on the practical control systems with microcontroller implementation. The core intent of this book is to help gain an accelerated learning path to practical control system engineering and transform control theory to an implementable control system through electronics. Illustrations are provided for most of the examples with fundamental mathematics along with simulations of the systems with their respective equations and stability calculations.
