Practical Examples of System Automation and Control

This chapter provides a practical demonstration of how a system’s automation can be achieved. Some specific examples presented include the automation of irrigation systems, waste segregator, gasifiers, biodiesel plants, biogas plants, lawn mowers, assembly line automation as well as the automation and control of the suspension system of a railcar. The details of the design and components required for the automation of these systems are highlighted. The chapter presents practical guided approaches by which system automation can be achieved depending on the end-users requirements. The practical examples highlight the integration of sensors (for measuring conditions/parameters), controllers (for processing inputs and decision-making) as well as actuators (for effecting changes) with minimal or no human interference. System automation is connected to the engineering field called mechatronics which is an interdisciplinary engineering branch comprising a combination of mechanical, computer, electrical and electronic systems. The automation of systems will enhance profitability, improved production rate, product quality, and safety.
