Microcomputer Control

With the development and maturity of intelligent buildings, energy conservation become a trend, lighting control systems are becoming increasingly popular. At the same time with the rapid development of electronic technology, microcomputer as a subject and core for embedded control systems, instead of the traditional conventional electronic circuits of the control system, based on single chip microcomputer control system has been widely used in intelligent building. This text directs against the power consuming wasting phenomenon of public place, regard AT89C51 as the core, propose a measurement for Pyroelectric infrared sensor and light combination of intelligent lighting control system. By judgment on the light intensity and indoor if someone automatically switch lights, achieve the purpose of energy saving.

Time Control

The progress of embedded control systems in the last several years has made possible the realization of highly-effective controllers in many domains. It is essential for such systems to provide effective performance at an affordable cost. Furthermore, real-time embedded control systems must have low energy consumption, as well as be reliable and timely. This research investigates primarily the feasibility of implementing an embedded real-time control system, based on a low-cost, commercially off-the-shelf (COTS) microcontroller platform. It explores real-time issues, such as the reliability and timely response, of such a system implementation. This work presents the development and performance evaluation of a novel real-time control architecture, based upon a BeagleBoard microcontroller, and applied into the PWM (pulse width modulation) control of a three-phase induction motor in a suction pump. The approach followed makes minimal use of general-purpose hardware (BeagleBone Black microcontroller board) and open-source software components (including Linux Operating System with PREEMPT_RT real-time support) for building a reliable real-time control system. The applicability of the proposed control system architecture is validated and evaluated in a real case study in manufacturing. The results provide sufficient evidence of the efficiency and reliability of the proposed approach into the development of a real-time control system based upon COTS components.

Different Levels

The chapter deals with UML-based design of Reconfigurable Embedded Control Systems (RECS). The different software architectural configurations of the control system are described as a set of inter-connected software components. A software agent is defined in order to handle dynamic reconfiguration scenarios. The agent has the ability to interact with users and to monitor the system’s environment in order to apply valid reconfiguration scenarios at different levels of the system’s architecture. In order to address all possible forms of reconfiguration, three architectural levels are defined. A set of UML-compliant metamodels are proposed in order to describe the knowledge about the reconfiguration agent, the system architecture, the reconfiguration scenarios, and the reconfiguration events. The validity of the reconfiguration scenarios is checked by using a UML-based environment that allows evaluation of the architectural and reconfiguration constraints. The proposed reconfiguration approach is applied to two industrial production systems, FESTO and ENAS.

And Performance

Along with the continuous development of embedded systems, embedded products take higher requirements on the scale and performance of system software, and contributing to the complexity of control algorithm. So it would take more time and expense to realize the control algorithm. Therefore, traditional design is out of date and cant cope with the modern development rhythm well. While the Model-Based Design, is an efficient design method to deal with complex embedded control systems. It provides a common development and test platform for the engineers. In this paper, we take the power windows control system as example; establish the algorithm model with the Simulink/Stateflow. Then we introduce these process of the control system design which is based on the Model-Based Design method, according to the result of the final experiment, we prove the efficiency of this method, providing a reference for the design of other complex control systems.
