Embedded Optimum Controller for Process Loop Using Arm Controller

Abstract: Embedded controllers are often the heart of an industrial control system or a process control application. They may also be at the centre of a portable data acquisition system or remote controller that allows an application to keep running even if its umbilical link to the outside world is cut. At the same as control systems is an important application class of embedded systems, feedback control is also an important basic technology that can be employed in the design of embedded real-time systems. Feedback control is a well established and mathematically well-founded theory that is ideal for handling uncertainties.The importance of reducing power consumption in embedded systems has now been widely recognized, and a large body of work has focused on estimating, managing, and reducing power consumption in various system components. For hardware design, techniques have been developed to estimate and optimize power consumption starting from the algorithm and architectural design phases, down to the circuit design and technology optimization steps. Application, semiconductor technology, cost, and time-to-market trends are causing a shift toward increased software content in embedded systems and systems- on-chip. As a result, designers and users of embedded software must be increasingly aware of power issues. While power dissipation is inherently a property of the underlying system hardware, knowledge of the embedded software that runs on the hardware is useful in order to analyze and improve the system’s power-consumption characteristics. Main Objective of this paper is to design a real-time (minimum time) optimum embedded controller for a closed loop process control system for controlling process temperature employing ARM controllers.
