  • Computers now form an integral part of most real-time control systems.With the advent of the microprocessors and microcontrollers in the last few decades the use of computers in control applications has been ever growing. Microcontrollers are single-chip computers which can be used to control real-time systems. Such controllers are also referred to as embedded real-time computers. These devices are low-cost, single-chip and easy to program.

  • From its title, you can see that this book is about real-time (computing, communication, and information) systems. Rather than pausing here to define the term precisely, which we will do in Chapter 2, let us just say for now that a real-time system is required to complete its work and deliver its services on a timely basis. Examples of real-time systems include digital

  • In this paper, some non-linear control algorithms have been verified through simulation and installed in atmega 32 microcontroller for 2D overhead crane system in the laboratory. The contribution of the paper is to evaluate the applicability of these laws and to create a practical research toolkit for students in the major of Automatic Control. The software of the proposed digital controllers has open structure to increase the ability of installing the new algorithms and the human-friendly interface on personal computer.

  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • Home theater projection has always promised greater viewer engagement, the prospect of a bigger, more exciting, more enveloping picture than just television. Greater engagement requires the screen to fill a larger field of view. This can only be achieved by sitting closer to the screen or increasing the overall screen size. But this has always run the risk of exposing image artifacts that pass without notice on smaller screens.

  • Simulated annealing has been applied to a wide range of problems: combinatorial and continuous optimizations. This work approaches a new class of problems in which the objective function is discrete but the parameters are continuous. This type of problem arises in rotational irregular packing problems. It is necessary to place multiple items inside a container such that there is no collision between the items, while minimizing the items occupied area. A feedback is proposed to control the next candidate probability distribution, in order to increase the number of accepted solutions.
