The book concerns a computer modelling of objects and processes in the industry are controlled. Control systems are formed of the basic devices. Most products are made up of independent electronic and mechanical components. Computer modelling of objects and processes is defined as the synergistic combination of precision mechanical, electronic, control, and systems engineering, in the design of products and manufacturing processes. Computer modelling of objects and processes responds to industry's increasing demand for engineers who are able to work across the boundaries of narrow engineering disciplines, to identify and use the proper combination of technologies for optimum solutions to today's increasingly challenging engineering problems. Computer modelling of objects and processes covers a wide range of application areas including consumer product design, instrumentation, manufacturing methods, motion control systems, computer integration, process and device control, integration of functionality with embedded microprocessor control, and the design of machines, devices and systems possessing a degree of computer-based intelligence.
