  • The NASA Mars Sojourner rover inspired this project . I followed the mission with great enthusiasm and witnessed a giant leap in robotics that day it began roaming the Martian terrain and sending images back to earth. Though I was in awe when the Viking missions of the 1970’s were in progress, we didn’t see that near real-time interaction with the craft .

  • A control system is a collection of components working together under the direction of some machine intelligence. In most cases, electronic circuits provide the intelligence, and electromechanical components such as sensors and motors provide the interface to the physical world. A good example is the modern automobile. Various sensors supply the on-board computer with information about the engine’s condition. The computer then calculates the precise amount of fuel to be injected into the engine and adjusts the ignition timing. T...

  • Most research in robotics centers on the control and equations of motion for multiple link and multiple degree-of-freedom armed, legged, or propelled systems. A great amount of effort is expended to plot exacting paths for systems built from commercially available motors and motor controllers. Deficiencies in component and subsystem performance are often undetected until the device is well past the initial design stage.

  • 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.

  • Custom controls and Web Parts can make you more productive by enabling you to create re-usable components for your WebForms. You can package up a piece of your user interface and re-use it within your Web site or across many Web sites. But that’s only one way that these controls make you more productive. If you’ve ever had an ASP.NET control that you wished worked slightly differently, you can now create the control that you want. When you build your own custom controls and Web Parts, you can have the control do as much (or as little) as you want....

  • Having discussed individual components of industrial servo drives from an operation point of view and a mathematical descriptive point of view, the next step is to combine these components into a block diagram for the complete servo drive. The block diagram is a powerful method of system analysis. In the block diagram each component in a servo system can be described by the ratio of its output to input. Thus the output of one component is the input to the next component.

  • The perspective of this book is that the steady - state separation model should also be the basis for developing the control confi guration for the column. Yes, a steady - state model! Although the technology to do so is widely available, extending to a dynamic model is not necessary for developing the column control confi guration. The most crucial component of every process control application is developing the piping and instrumentation (P & I) diagram that defi nes the control confi guration for the process and for each unit operation, such as distillation, within that process.
